Subject: [PATCH v7 9/9] mtd: cfi_cmdset_0002: Disable write buffer functions if FORCE_WORD_WRITE is 1
Date: Thu, 20 Jun 2019 01:50:01 +0900 [thread overview]
Message-ID: <20190619165001.28410-10-ikegami.t@gmail.com> (raw)
In-Reply-To: <20190619165001.28410-1-ikegami.t@gmail.com>
Some write buffer functions are not used when FORCE_WORD_WRITE is set to 1.
So the compile warning messages are output if FORCE_WORD_WRITE is 1. To
resolve this disable the write buffer functions if FORCE_WORD_WRITE is 1.
