[PATCH v2 18/30] misc: mic: scif: scif_api: Remove set but unused variable 'read_size'

From: Lee Jones
Date: Wed Jul 01 2020 - 04:32:56 EST


'read_size' appears to have been assigned, but never used since the
SCIF messaging and node enumeration APIs were introduced in 2015.
Makes sense to simply remove it.

Fixes the following W=1 warning:

drivers/misc/mic/scif/scif_api.c: In function â_scif_recvâ:
drivers/misc/mic/scif/scif_api.c:1000:6: warning: variable âread_sizeâ set but not used [-Wunused-but-set-variable]
1000 | int read_size;
| ^~~~~~~~~
