[PATCH] agp: remove set but not used variable 'size'

From: yu kuai
Date: Wed Nov 27 2019 - 07:27:32 EST


Fixes gcc '-Wunused-but-set-variable' warning:

drivers/char/agp/generic.c: In function âagp_generic_create_gatt_tableâ:
drivers/char/agp/generic.c:853:6: warning: variable âsizeâ set but not
used [-Wunused-but-set-variable]

It is never used, so can be removed.
