From 452dfcc3b461c1bfbc2126623f42f551000a9ca3 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 27 Mar 2025 15:33:09 +0000 Subject: [PATCH] mtd: spi-nor-tiny: annotate switch/case fallthrough The SPI NOR code uses an implicit switch/case fallthrough when checking different vendors to determine how to deal with extended addressig modes. Add our "fallthrough;" statement-like macro before some label in the 4-byte addressing mode code, to avoid a warning when GCC's -Wimplicit-fallthrough warning option is enabled.
