R. Silva" , Kees Cook List-Id: linux-mmc@vger.kernel.org In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/mmc/host/sdhci-xenon-phy.c: In function ‘xenon_emmc_phy_slow_mode’: drivers/mmc/host/sdhci-xenon-phy.c:527:47: warning: this statement may fall through [-Wimplicit-fallthrough=] if ((priv->init_card_type == MMC_TYPE_SDIO) || ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~ params->slow_mode) { ~~~~~~~~~~~~~~~~~ drivers/mmc/host/sdhci-xenon-phy.c:534:2: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
