[linux-next:master 8662/14447] drivers/soc/fsl/qe/gpio.c:42:34: sparse: sparse: incorrect type in assignment (different base types)

Hi Christophe,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head:   5e6de6a2b522f659defacb1551d0465ba6ce13cf
commit: 21d055109b2352542ac293872ca9113b42b6c55e [8662/14447] powerpc: Move CONFIG_QE_GPIO to SoC
config: parisc-randconfig-r111-20260813 (https://download.01.org/0day-ci/archive/20260813/[email protected]/config)
compiler: hppa-linux-gcc (GCC) 14.3.0
sparse: v0.6.5-rc1
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20260813/[email protected]/reproduce)
