Subject: [PATCH] staging: fbtft: Remove set but not used variable 'ret'

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

drivers/staging/fbtft/fb_ili9320.c: In function read_devicecode:
drivers/staging/fbtft/fb_ili9320.c:25:6: warning: variable ret set but not used [-Wunused-but-set-variable]

ret is never used, so remove it.
