From 9882b5375df532acb2c2399a90d882461112e612 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Fri, 1 Jun 2018 12:03:25 +0200 Subject: [PATCH] mtd: m25p80: Use SPI_MEM_OP_NO_DUMMY instead of SPI_MEM_OP_DUMMY(0, x) SPI_MEM_OP_DUMMY(0, x) means there's 0 dummy bytes to send, which is similar to SPI_MEM_OP_NO_DUMMY except it's less clear. Use SPI_MEM_OP_NO_DUMMY instead of SPI_MEM_OP_DUMMY(0, x) in m25p80_write(). Also stop updating op.dummy.buswidth since this value is only meaningful if you have dummy bytes.
