Subject: HID: alps: fix error return code in alps_input_configured()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=46a41b512f6800b531e94bdf5f1ca0e226492d91;p=linux-beck.git

HID: alps: fix error return code in alps_input_configured()

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

While at it, remove redundant input_free_device(NULL) call.
