Subject: staging: comedi: me_daq: replace 'result' and 'error' with 'ret'
X-Git-Tag: firefly_0821_release~3680^2~1519^2~938
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4bb153b4e4f9e11ac7e9b58d3957dba9a3c3fd2e;p=firefly-linux-kernel-4.4.55.git

staging: comedi: me_daq: replace 'result' and 'error' with 'ret'

Two local variables are used in me_attach_pci() to check for errors
when calling other functions, 'result' and 'error'. Remove both of
them and just use a common 'ret' variable.
