[PATCH 0/2] mfd: tps65217: Handle IRQ initialization errors

Posted by Жамбакиев Радий Рикардинович 1 month, 1 week ago

The tps65217 MFD driver ignores two error conditions when setting up
its interrupt handling, which can leave the driver bound in a broken
state. This series adds the missing error checks.

Patch 1 fixes a kernel crash: if the irq domain creation fails,
probe ignores the error and a later module unload dereferences the
NULL irq domain in tps65217_remove().

Patch 2 checks the error when masking all interrupt sources, so the
driver's software mask cannot diverge from the hardware state.
