Subject: [PATCH] nfc: st95hf: remove redundant pointers 'dev' and 'nfcddev'

From: Colin Ian King <colin.king@...onical.com>

Pointers 'dev' and 'nfcddev' are being assigned but are never used
hence they are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'dev' set but not used [-Wunused-but-set-variable]
warning: variable 'nfcddev' set but not used [-Wunused-but-set-variable]
