From 1cc7c7e119a31c64cf64d887374c95b58ffe9993 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 31 Aug 2024 22:31:44 +0200 Subject: [PATCH] mtd: spi: renesas: Write DREAR register once Instead of writing DREAR with 0 first and then overwriting DREAR again in case of 4 byte addressing mode, write DREAR in every case once with the correct content right away. No functional change.
