Subject: i2c: mux: Fix error path in i2c-arb-gpio
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20%24style.Permalink%20%7D%7D?a=commitdiff_plain;h=6d06fdb93c13e3b989091918aaa60b04b347ab55;p=u-boot.git

i2c: mux: Fix error path in i2c-arb-gpio

There is no reason to use goto and just call return. Better is to call
return directly which is done for some if/else parts.

Also make no sense to setup ret to -ETIMEDOUT and then to 0.
Return timeout directly.
