ASoC: wm8962: balance pm_runtime_enable
pm_runtime_enable is called in probe to enable runtime PM for wm8962 codec, but pm_runtime_disable isn't called in remove callback, nor is called in error path if probe fails after runtime PM is enabled, this causes unbalanced pm_runtime_enable. This patch Adds pm_runtime_disable in remove callback and error path, to balance pm_runtime_enable.
