powerpc/pmac: replace current->state by set_current_state()

2015-03-25T05:53:28+00:00

Use helper functions to access current->state.
Direct assignments are prone to races and therefore buggy.

current->state = TASK_RUNNING can be replaced by __set_current_state()

Thanks to Peter Zijlstra for the exact definition of the problem.

drivers/macintosh: Delete an unnecessary check before the function call "of_node_put"

2015-03-25T05:53:27+00:00

The of_node_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40+00:00

ppc has special instruction forms to efficiently load and store values
in non-native endianness.  These can be accessed via the arch-specific
{ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h.

However, gcc is perfectly capable of generating the byte-reversing
load/store instructions when using the normal, generic cpu_to_le*() and
le*_to_cpu() functions eaning the arch-specific functions don't have much
point.

Worse the "le" in the names of the arch specific functions is now
misleading, because they always generate byte-reversing forms, but some
ppc machines can now run a little-endian kernel.

To start getting rid of the arch-specific forms, this patch removes them
from all the old Power Macintosh drivers, replacing them with the
generic byteswappers.

powerpc/via-pmu: fix OF node leak in Keylargo init

2015-03-17T00:56:51+00:00

If we of_find_node_by_name() then we must of_node_put() too.

powerpc/via-pmu: fix error path in find_via_pmu()

2015-03-17T00:56:34+00:00

Cleanup was not in the reverse order from the set-up, so not all
the gotos made sense, and also it was being avoided completely upon
failure of init_pmu().

macintosh: therm_pm72: delete deprecated driver

2014-12-19T18:32:47+00:00

The new driver is around for more than 2 years now, so the old one can
go. Getting rid of it helps the removal of the legacy .attach_adapter
callback of the I2C subsystem.

macintosh: drop owner assignment from platform_drivers

2014-10-20T14:20:43+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.
