Subject: staging: dgap: remove redundant error value check
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dfa30ac13952ee0c2918090815688a909ad074f0;p=openwrt%2Fstaging%2Fblogic.git

staging: dgap: remove redundant error value check

The retval in dgap_block_til_ready() is initialized to zero,
and if no error has occurred in this function, the retval has a zero.
So it doesn't need to check "retval" itself.
