wm8350_reg_lock()

The WM8350 has a hardware lock which can be used to prevent writes to some registers (generally those which can cause particularly serious problems if misused). This function enables that lock.

wm8350_reg_unlock()

The WM8350 has a hardware lock which can be used to prevent writes to some registers (generally those which can cause particularly serious problems if misused). This function disables that lock so updates can be performed. For maximum safety this should be done only when required.
