powerpc/powermac: constify device_node in of_irq_parse_oldworld()

2022-05-22T05:59:54Z

The of_irq_parse_oldworld() does not modify passed device_node so make it a pointer to const for safety. Drop the extern while modifying the line.

powerpc/powermac: add missing g5_phy_disable_cpu1() declaration

2022-05-22T05:59:54Z

g5_phy_disable_cpu1() is used outside of platforms/powermac/feature.c, so it should have a declaration to fix W=1 warning: arch/powerpc/platforms/powermac/feature.c:1533:6: error: no previous prototype for ‘g5_phy_disable_cpu1’ [-Werror=missing-prototypes] Signed-off-by: Krzysztof Kozlowski Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20210924105653.46963-1-krzysztof.kozlowski@canonical.com

powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

powerpc: No need to initialise statics to 0

2022-05-04T09:37:45Z

Static variables do not need to be initialised to 0, because compiler will initialise all uninitialised statics to 0. Thus, remove the unneeded initializations.

powerpc: use strscpy to replace strlcpy

2022-05-04T09:37:44Z

The strlcpy should not be used because it doesn't limit the source length. As linus says, it's a completely useless function if you can't implicitly trust the source string - but that is almost always why people think they should use it! All in all the BSD function will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, We prefer using strscpy instead of strlcpy.
