staging: rtl8192e: Replace RT_TRACE(COMP_ERR, ...) with netdev_*
- Use netdev_* with log level depending on how serious error is
- Rework some messages to be more readable
- Pass net_device where needed for pretty prints
Remove the following private variables:
- force_mic_error - changes force_mic_error that is not used
- radio - changes sw_radio_on that is not used
- adhoc_peer_list - unimplemented
- firm_ver - unimplemented
Fix most of simple LONG_LINE warnings. None of the changes should affect
behaviour of code, so several modifications are included in this patch:
- Code is reindented where needed
- Local variable names are compacted (priv -> p)
- Unnecessary casts are removed
- Nested ifs are replaced with logical and
- a = b = c = d expressions are split
- Replace if/then series with clamp_t()
- Removed unneeded scopes
- Use netdev_dbg or netdev_vdbg instead of RTLLIB_DEBUG()
- Reformat some messages for better readability
- Remove RTLLIB_DEBUG messages that make no sense
- Pass extra argument (rtllib_device) to rtllib_parse_qos_info_param_IE()
and update_network()
- Replace RTLLIB_DEBUG_QOS() with netdev_dbg()
- Remove RTLLIB_DEBUG_QOS()
- Extract frame_ctl once and use it as variable.
- Drop endian conversion in is_beacon() function
(used in simplified function only)
- Simplify debug messages
- Invert STYPE checks in debug messages - it is valid
as only BEACON and PROBE_RESP are allowed
staging: rtl8192e: Replace RTLLIB_DEBUG(DL_ERR) with netdev_*()
Replace all RTLLIB_DEBUG(RTLLIB_DL_ERR, *) calls with netdev_err()
for errors that really should be reported to user.
Use netdev_warn() for the rest.
Rephrase some of the messages to make them more readable/compact.
staging: rtl8192e: Fix DEEP_INDENTATION warning in rtllib_parse_info_param()
Move MFIE_TYPE_GENERIC handler to rtllib_parse_mife_generic() function.
Code was not altered significantly, therefore in some places it generates
LONG_LINE checkpatch.pl warnings.
Replace memcpy() with ether_addr_copy() where possible to make
checkpatch.pl happy.
Change was target tested (download 1Mb file over WPA2 network)
with BUG trap for unaligned addresses in ether_addr_copy()
staging: rtl8192e: Make ethernet addresses properly aligned
Reorder ethernet addresses allocated on stack or in non-packed

Use ETH_ALEN as array length in places where it was hardcoded to 6.
Alignment verified using pahole where possible and target-tested
with BUG_ON() trap in ether_addr_copy.

staging: fbtft: Add support for Himax HX8357D controller
The Himax HX8357D is used e.g. by the Adafruit PITFT Plus 3.5".
Adafruit added HX8357D support to an own fork of fbtft and support
Raspbian only (https://github.com/adafruit/adafruit-rpi-fbtft/).
They don't intend to push it upstream but gave me the ok to do so.
Original author: Sean Cross <xobs@kosagi.com>
I just applied small changes to the driver to align it with the other
fbtft drivers.
- add "compatible" argument to FBTFT_REGISTER_DRIVER call
- add missing MODULE_ALIAS declarations
Tested successfully with this display on an RPI2 under Arch Linux ARM
(kernel 3.18.13).
lustre_ext_acl_xattr_reduce_space() declares old_size, but never uses it
and gcc 5.x likes to complain about this, so remove it as it's not used
at all.
staging: panel: use schedule_timeout_interruptible()

consolidation with schedule_timeout_*() recommended
This is a 1:1 conversion with respect to schedule_timeout() to the
schedule_timeout_interruptible() helper only - so only an API
consolidation to improve readability. The timeout was being passed
as (ms * HZ + 999) / 1000 but that simply looks wrong - rather than
"manual" converting to jiffies, msecs_to_jiffies which handles all
corner-cases correctly, was used.
Patch was compile tested with x86_64_defconfig + CONFIG_STAGING=y,
CONFIG_PARPORT=m, CONFIG_PANEL=m

returned error, leaving debugfs entry in the filesystem.

jump to it in case of allocation failure, and free debugfs entries.

As the first argument of gf_write64() was of type unsigned long, and as
some calls to gf_write64() were casting the first argument from void *
to u64 the compiler and/or sparse were printing warnings for casts of
wrong sizes when compiling for i386.
This patch changes the type of the first argument of gf_write64() to
const void *, and update calls to the function. This change fixed the
warnings and allowed to remove casts from 3 calls to gf_write64().
In addition gf_write64() was renamed to gf_write_ptr() as the name was
misleading because it only writes 32 bits on 32 bit systems.
gf_write_dma_addr() was added to handle dma_addr_t values which is
