Subject: [PATCH] gpio: mxs: fix Wvoid-pointer-to-enum-cast warning
Date:   Thu, 10 Aug 2023 11:59:49 +0200

'devid' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  gpio-mxs.c:274:16: error: cast to smaller integer type 'enum mxs_gpio_id' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
