fbdev: Move fbdev drivers from strlcpy to strscpy

2022-08-24T20:06:15+00:00

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

Merge tag 'arm-multiplatform-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2022-06-02T22:23:54+00:00

Pull more ARM multiplatform updates from Arnd Bergmann:
 "The second part of the multiplatform changes now converts the
  Intel/Marvell PXA platform along with the rest. The patches went
  through several rebases before the merge window as bugs were found, so
  they remained separate.

  This has to touch a lot of drivers, in particular the touchscreen,
  pcmcia, sound and clk bits, to detach the driver files from the
  platform and board specific header files"

ARM: pxa: move regs-lcd.h into driver

2022-04-19T14:29:03+00:00

Only the pxafb driver uses this header, so move it into the
same directory. The SMART_* macros are required by some
platform data definitions and can go into the
linux/platform_data/video-pxafb.h header.

ARM: pxa: stop using mach/bitfield.h

2022-04-19T14:28:04+00:00

There are two identical copies of mach/bitfield.h, one for
mach-sa1100 and one for mach-pxa. The pxafb driver only
makes use of two macros, which can be trivially open-coded
in the header.

ARM: pxa: split up mach/hardware.h

2022-04-19T14:27:05+00:00

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate  and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

video: fbdev: pxafb: Use correct return value for pxafb_probe()

2020-06-01T13:15:23+00:00

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.

video: pxafb: Fix the function used to balance a 'dma_alloc_coherent()' call

2020-06-01T13:15:22+00:00

'dma_alloc_coherent()' must be balanced by a call to 'dma_free_coherent()'
not 'dma_free_wc()'.
The correct dma_free_ function is already used in the error handling path
of the probe function.

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
