From: Pan Bian Date: Sun, 4 Dec 2016 05:40:06 +0000 (-0200) Subject: [media] media: pci: meye: set error code on failures X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2ce899423c150c38e2b1590a83a2e22f8c77b60a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] media: pci: meye: set error code on failures The value of return variable ret is 0 on some error paths, for example, when pci_resource_start() returns a NULL pointer. 0 means no error in this context, which is contrary to the fact. This patch fixes the bug.
