net: dsa: b53: check for timeout
[ Upstream commit 774d977abfd024e6f73484544b9abe5a5cd62de7 ]
clang static analysis reports this problem
b53_common.c:1583:13: warning: The left expression of the compound
assignment is an uninitialized value. The computed value will
also be garbage
ent.port &= ~BIT(port);
~~~~~~~~ ^
ent is set by a successful call to b53_arl_read(). Unsuccessful
calls are caught by an switch statement handling specific returns.
b32_arl_read() calls b53_arl_op_wait() which fails with the
unhandled -ETIMEDOUT.
So add -ETIMEDOUT to the switch statement. Because
b53_arl_op_wait() already prints out a message, do not add another
one.
