From 22c525b976778cce5bb6f8fdcc70046168c54b1a Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:11 +0100 Subject: [PATCH] ide: remove ata_status_t and atapi_status_t Remove ata_status_t (unused) and atapi_status_t. While at it: * replace 'HWIF(drive)' by 'drive->hwif' (or just 'hwif' where possible) Acked-by: Sergei Shtylyov Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/ide-floppy.c | 14 ++++++------- drivers/ide/ide-lib.c | 21 ++++++++----------- drivers/ide/ide-tape.c | 34 +++++++++++++++---------------- drivers/scsi/ide-scsi.c | 9 ++++---- include/linux/ide.h | 44 ---------------------------------------- 5 files changed, 37 insertions(+), 85 deletions(-) diff --git a/drivers/ide/ide-floppy.c b/drivers/ide/ide-floppy.c index 53f90257a8f0..7b94c7aff256 100644 --- a/drivers/ide/ide-floppy.c +++ b/drivers/ide/ide-floppy.c @@ -788,12 +788,12 @@ static void idefloppy_retry_pc (ide_drive_t *drive) static ide_startstop_t idefloppy_pc_intr (ide_drive_t *drive) { idefloppy_floppy_t *floppy = drive->driver_data; - atapi_status_t status; atapi_bcount_t bcount; atapi_ireason_t ireason; idefloppy_pc_t *pc = floppy->pc; struct request *rq = pc->rq; unsigned int temp; + u8 stat; debug_log(KERN_INFO "ide-floppy: Reached %s interrupt handler\n", __FUNCTION__); @@ -809,16 +809,16 @@ static ide_startstop_t idefloppy_pc_intr (ide_drive_t *drive) } /* Clear the interrupt */ - status.all = HWIF(drive)->INB(IDE_STATUS_REG); + stat = drive->hwif->INB(IDE_STATUS_REG); - if (!status.b.drq) { /* No more interrupts */ + if ((stat & DRQ_STAT) == 0) { /* No more interrupts */ debug_log(KERN_INFO "Packet command completed, %d bytes " "transferred\n", pc->actually_transferred); clear_bit(PC_DMA_IN_PROGRESS, &pc->flags); local_irq_enable_in_hardirq(); - if (status.b.check || test_bit(PC_DMA_ERROR, &pc->flags)) { + if ((stat & ERR_STAT) || test_bit(PC_DMA_ERROR, &pc->flags)) { /* Error detected */ debug_log(KERN_INFO "ide-floppy: %s: I/O error\n", drive->name); @@ -1632,14 +1632,14 @@ static int idefloppy_get_format_progress(ide_drive_t *drive, int __user *arg) /* Else assume format_unit has finished, and we're ** at 0x10000 */ } else { - atapi_status_t status; unsigned long flags; + u8 stat; local_irq_save(flags); - status.all = HWIF(drive)->INB(IDE_STATUS_REG); + stat = drive->hwif->INB(IDE_STATUS_REG); local_irq_restore(flags); - progress_indication = !status.b.dsc ? 0 : 0x10000; + progress_indication = ((stat & SEEK_STAT) == 0) ? 0 : 0x10000; } if (put_user(progress_indication, arg)) return (-EFAULT); diff --git a/drivers/ide/ide-lib.c b/drivers/ide/ide-lib.c index 3bae2c46924f..dc7e539b4d0b 100644 --- a/drivers/ide/ide-lib.c +++ b/drivers/ide/ide-lib.c @@ -562,27 +562,24 @@ static u8 ide_dump_ata_status(ide_drive_t *drive, const char *msg, u8 stat) static u8 ide_dump_atapi_status(ide_drive_t *drive, const char *msg, u8 stat) { unsigned long flags; - - atapi_status_t status; atapi_error_t error; - status.all = stat; error.all = 0; local_irq_save(flags); printk("%s: %s: status=0x%02x { ", drive->name, msg, stat); - if (status.b.bsy) + if (stat & BUSY_STAT) printk("Busy "); else { - if (status.b.drdy) printk("DriveReady "); - if (status.b.df) printk("DeviceFault "); - if (status.b.dsc) printk("SeekComplete "); - if (status.b.drq) printk("DataRequest "); - if (status.b.corr) printk("CorrectedError "); - if (status.b.idx) printk("Index "); - if (status.b.check) printk("Error "); + if (stat & READY_STAT) printk("DriveReady "); + if (stat & WRERR_STAT) printk("DeviceFault "); + if (stat & SEEK_STAT) printk("SeekComplete "); + if (stat & DRQ_STAT) printk("DataRequest "); + if (stat & ECC_STAT) printk("CorrectedError "); + if (stat & INDEX_STAT) printk("Index "); + if (stat & ERR_STAT) printk("Error "); } printk("}\n"); - if (status.b.check && !status.b.bsy) { + if ((stat & (BUSY_STAT|ERR_STAT)) == ERR_STAT) { error.all = HWIF(drive)->INB(IDE_ERROR_REG); printk("%s: %s: error=0x%02x { ", drive->name, msg, error.all); if (error.b.ili) printk("IllegalLengthIndication "); diff --git a/drivers/ide/ide-tape.c b/drivers/ide/ide-tape.c index 90e902d233cf..c91039505436 100644 --- a/drivers/ide/ide-tape.c +++ b/drivers/ide/ide-tape.c @@ -1848,15 +1848,14 @@ static ide_startstop_t idetape_pc_intr (ide_drive_t *drive) { ide_hwif_t *hwif = drive->hwif; idetape_tape_t *tape = drive->driver_data; - atapi_status_t status; atapi_bcount_t bcount; atapi_ireason_t ireason; idetape_pc_t *pc = tape->pc; - unsigned int temp; #if SIMULATE_ERRORS static int error_sim_count = 0; #endif + u8 stat; #if IDETAPE_DEBUG_LOG if (tape->debug_level >= 4) @@ -1865,10 +1864,10 @@ static ide_startstop_t idetape_pc_intr (ide_drive_t *drive) #endif /* IDETAPE_DEBUG_LOG */ /* Clear the interrupt */ - status.all = HWIF(drive)->INB(IDE_STATUS_REG); + stat = hwif->INB(IDE_STATUS_REG); if (test_bit(PC_DMA_IN_PROGRESS, &pc->flags)) { - if (HWIF(drive)->ide_dma_end(drive) || status.b.check) { + if (hwif->ide_dma_end(drive) || (stat & ERR_STAT)) { /* * A DMA error is sometimes expected.
