[PATCH] ARM: OMAP2+: PM: Denote the cpuidle tracepoints as _rcuidle()
The cpuidle tracepoints are called within a rcu_idle_exit() section, and must be denoted with the _rcuidle() version of the tracepoint.

[PATCH] ARM: OMAP: Remove duplicated operand in OR operation
Commit b483a4a5a711 ("ARM: OMAP4+: hwmod data: Don't prevent RESET of
USB Host module") added the SYSC_HAS_RESET_STATUS flag to both OMAP4
and OMAP5 USB host module hwmon sysconfig but that flag was already
set for OMAP5. So now the flag appears twice in the expression.

[PATCH v3] ASoC: soc-core: Fix sparse warning in be32_to_cpup() call
Store return value of of_get_property() to a pointer of __be32 type as
device tree has big endian type. This fixes a sparse warning couple of
lines later when be32_to_cpup() is used to convert from big endian to
cpu endian.
The whole conversion is not really necessary, as we are only checking
if the value is zero or not, but I wanted to add it to remind in the
future that the data has to be converted before use. Compiler should
optimize the unnecessary operations away.

So here is a v3 of the same one liner patch.
