From aea3877e24f3acc6145094848dbb85f9ce85674a Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 25 Sep 2018 11:46:55 +0200 Subject: [PATCH] spi: spi-mem: Fix inverted logic in op sanity check On r8a7791/koelsch: m25p80 spi0.0: error -22 reading 9f m25p80: probe of spi0.0 failed with error -22 Apparently the logic in spi_mem_check_op() is wrong, rejecting the spi-mem operation if any buswidth is valid, instead of invalid.
