From 0438ee7080ac83a6a831c52bc4e8c29dc2306e95 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Tue, 18 Feb 2014 09:43:53 +0100 Subject: [PATCH] HID: cp2112: fix incorrect error propagation in cp2112_xfer() Both cp2112_read_req() and cp2112_write_req() are returning negative value in cases of error, but cp2112_xfer() is storing the return value into unsigned size_t-typed 'count'. Fix this by making 'count' signed type.
