From dfeae1073583dc35c33b32150e18b7048bbb37e6 Mon Sep 17 00:00:00 2001 From: Tokunori Ikegami <ikegami@allied-telesis.co.jp> Date: Wed, 30 May 2018 18:32:26 +0900 Subject: mtd: cfi_cmdset_0002: Change write buffer to check correct value From: Tokunori Ikegami <ikegami@allied-telesis.co.jp> commit dfeae1073583dc35c33b32150e18b7048bbb37e6 upstream. For the word write it is checked if the chip has the correct value. But it is not checked for the write buffer as only checked if ready. To make sure for the write buffer change to check the value. It is enough as this patch is only checking the last written word. Since it is described by data sheets to check the operation status.
