| |
In many of clk_disable() implementations, it is a no-op for a NULL pointer input, but this is one of the exceptions.
Making it treewide consistent will allow clock consumers to call clk_disable() without NULL pointer check.

Changes in v5: None Changes in v4: - Split into per-arch patches
Changes in v3: - Return only when clk is NULL. Do not take care of error pointer.
Changes in v2: - Rebase on Linux 4.6-rc1
