Subject: isdn: i4l: isdn_common: Fix set-but-unused variables.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=50a7c114c2673f3fcbb0ba5d659049156e1ccd50;p=linux-beck.git

isdn: i4l: isdn_common: Fix set-but-unused variables.

The variable 'ch' is set but unused in isdn_capi_rec_hl_msg().  Just
kill it off.

Similarly for 'chidx' in isdn_ioctl() and 'di' in
isdn_capi_rec_hl_msg().
