Subject: Re: [PATCH v2] firmware_loader: Abort new fw load request once
firmware core knows about reboot
Hi Mukesh,
kernel test robot noticed the following build errors:
[auto build test ERROR on driver-core/driver-core-testing]
[also build test ERROR on driver-core/driver-core-next driver-core/driver-core-linus linus/master v6.6-rc4 next-20231004]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
