Hi, Thank you for sending the patch over! > fixed the following coccicheck: > ./arch/x86/pci/mmconfig-shared.c:464:9-10: WARNING: return of 0/1 in > function 'is_mmconf_reserved' with return type bool > ./arch/x86/pci/mmconfig-shared.c:493:5-6: WARNING: return of 0/1 in > function 'is_mmconf_reserved' with return type bool > ./arch/x86/pci/mmconfig-shared.c:501:9-10: WARNING: return of 0/1 in > function 'is_mmconf_reserved' with return type bool > ./arch/x86/pci/mmconfig-shared.c:522:5-6: WARNING: return of 0/1 in > function 'is_mmconf_reserved' with return type bool [...] Looks good, although a few small nitpicks: you should capitalise the subject line so that it matches the style used in previous commits, and the commit message could also be improved in terms of style and also explaining what and why this patch is fixing the return type (aside of just addressing report from Cocinelle). Other than that, Reviewed-by: Krzysztof Wilczyński <kw@linux.com> Thank you! Krzysztof
