[PATCH 0/2] ASoC: adau1372: Fix error handling in adau1372_set_power()

[Jihed Chaibi <jihed.chaibi.dev@gmail.com>]

adau1372_set_power() had two related error handling issues in its enable
path: clk_prepare_enable() was called but its return value discarded, and
adau1372_enable_pll() was a void function that silently swallowed lock
failures, leaving mclk enabled and adau1372->enabled set to true despite
the device being in a broken state.

Patch 1 fixes the unchecked clk_prepare_enable() by making
adau1372_set_power() return int and propagating the error.

Patch 2 converts adau1372_enable_pll() to return int and adds a
clk_disable_unprepare() unwind in adau1372_set_power() if PLL lock fails.
