From f8fb952fd409a4c854a66473c11d35b4e5e9c2eb Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 24 Jul 2013 11:37:29 -0700 Subject: [PATCH] msm_serial: Fix sparse warnings drivers/tty/serial/msm_serial.c:302:6: warning: symbol 'msm_set_mctrl' was not declared. Should it be static? drivers/tty/serial/msm_serial.c:597:17: warning: incorrect type in argument 2 (different address spaces) drivers/tty/serial/msm_serial.c:597:17: expected void volatile [noderef] *addr drivers/tty/serial/msm_serial.c:597:17: got unsigned int * drivers/tty/serial/msm_serial.c:608:33: warning: incorrect type in argument 1 (different address spaces) drivers/tty/serial/msm_serial.c:608:33: expected void volatile [noderef] *addr drivers/tty/serial/msm_serial.c:608:33: got unsigned int *gsbi_base drivers/tty/serial/msm_serial.c:648:37: warning: incorrect type in assignment (different address spaces) drivers/tty/serial/msm_serial.c:648:37: expected unsigned int *gsbi_base drivers/tty/serial/msm_serial.c:648:37: got void [noderef] * Mark the ioremapped memory as __iomem and use writel instead of iowrite because we're not dealing with PCI devices. Also, mark msm_set_mctrl() static because it isn't used outside this file.
