Subject: [PATCH] staging: rts5208: Convert kmap() to kmap_local_page()
Date: Mon, 28 Mar 2022 13:24:40 +0200 [thread overview]
Message-ID: <20220328112440.17756-1-fmdefrancesco@gmail.com> (raw)
The use of kmap() is being deprecated and kmap_local_page() is faster.
Use kmap_local_page() in place of kmap().
