Subject: [PATCH 6.8 622/715] coccinelle: device_attr_show: Remove useless expression STR

From: Li Zhijian <lizhijian@...itsu.com>

[ Upstream commit 173f6cd384ae27bb57af8cc5201b4f4a137d6e55 ]

Commit ff82e84e80fc ("coccinelle: device_attr_show: simplify patch case")
simplifies the patch case, as a result, STR is no longer needed.

This also helps to fix below coccicheck warning:
> warning: rp: metavariable STR not used in the - or context code
