[PATCH AUTOSEL 4.19 562/671] cxgb4: Signedness bug in init_one()

From: Dan Carpenter <redacted>

[ Upstream commit 286183147666fb76c057836c57d86e9e6f508bca ]

The "chip" variable is an enum, and it's treated as unsigned int by GCC
in this context so the error handling isn't triggered.

Fixes: e8d452923ae6 ("cxgb4: clean up init_one")
