[PATCH] PM / OPP: Remove useless check

by Viresh Kumar

Regulators are optional for devices using OPPs and the OPP core shouldn't be printing any errors for such missing regulators. It was fine before the commit 0c717d0f9cb4, but that failed to update this part of the code to remove an 'always true' check and an extra unwanted print message. Fix that now.

[PATCH] PM / OPP: Move CONFIG_OF dependent code in a separate file

by Viresh Kumar

Recently few issues were noticed in the code where CONFIG_OF wasn't consistently used for many routines. The core file is big enough now and ifdef hackery makes it less readable. Move OF specific code to another file and compile that only if CONFIG_OF is enabled. Compile-tested: - For ARM (exynos) with CONFIG_OF enabled - For X86 with CONFIG_OF disabled (have to enable CONFIG_PM_OPP separately) No functional changes.
