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.
