Re: [PATCH] mfd: ene-kb3930: Fix potential NULL pointer dereference

[Chenyuan Yang]

Hi Krzysztof,

This was caught by our static analysis tool because
devm_gpiod_get_array_optional() can return a NULL pointer in
low-memory situations. It's essentially the same scenario described
here:
https://patchwork.kernel.org/project/linux-fbdev/patch/20240114143921.550736-1-andriy.shevchenko@xxxxxxxxxxxxxxx/.

Best,
Chenyuan
