Could you help fix this lkp issue and I could re-apply the patch?
config: arm-randconfig-c034-20221024 (attached as .config)
compiler: arm-linux-gnueabi-gcc (GCC) 12.1.0
If you fix the issue, kindly add following tag where applicable
| Reported-by: kernel test robot <lkp@xxxxxxxxx>
cocci warnings: (new ones prefixed by >>)
>> drivers/fpga/lattice-sysconfig-spi.c:33:7-14: WARNING opportunity for kmemdup
Thanks,
