From: Pan Bian Date: Sun, 4 Dec 2016 05:21:42 +0000 (+0800) Subject: scsi: be2iscsi: set errno on error path X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=29b33252751b430e400a987667a826ffcd2741f4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git scsi: be2iscsi: set errno on error path Variable ret is reset in the loop, and its value will be 0 during the second and after repeat of the loop. If pci_alloc_consistent() returns a NULL pointer then, it will leaves with return value 0. 0 means no error, which is contrary to the fact. This patches fixes the bug, explicitly assigning "-ENOMEM" to return variable ret on the path that the call to pci_alloc_consistent() fails.
