Subject: HID: simplify error handling in hid_input_report()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f77e347bd44e3640bdc56003b7402c63ddb1241d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

HID: simplify error handling in hid_input_report()

The handling of failed debugging buffer allocation got overly
complicated. We simply want to skip the debugging code if allocation
fails and go on with event processing.
