Subject: serial: mxs-auart: Remove unneeded zeroing of 'ret'
X-Git-Tag: v4.0-rc1~81^2~44
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5f9ba5b693ed6d639a3e6b47f4c6cd80e36f2547;p=karo-tx-linux.git

serial: mxs-auart: Remove unneeded zeroing of 'ret'

There is no need to explicitly zero the 'ret' variable as it is properly
initialized in a few lines below as:

ret = serial_mxs_probe_dt(s, pdev);

Remove the unneeded zeroing of 'ret'.
