From 2ea370a9173f4a3c80b24221049359a5d1518bc0 Mon Sep 17 00:00:00 2001 From: Vignesh Raghavendra Date: Tue, 25 Aug 2020 22:55:06 +0530 Subject: [PATCH] spi: spi-cadence-quadspi: Populate get_name() interface Implement get_name() interface of spi_controller_mem_ops so as to avoid changing of mtd->name due to driver being moved over to spi-mem framework from SPI NOR. This avoids breaking of MTD cmdline args being passed by bootloaders which maybe using old driver name.
