mfd: db8500-prcmu: Mark expected switch fall-throughs
Mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/mfd/db8500-prcmu.c: In function 'dsiclk_rate': drivers/mfd/db8500-prcmu.c:1592:7: warning: this statement may fall through [-Wimplicit-fallthrough=] div *= 2; ~~~~^~~~ drivers/mfd/db8500-prcmu.c:1593:2: note: here case PRCM_DSI_PLLOUT_SEL_PHI_2: ^~~~ drivers/mfd/db8500-prcmu.c:1594:7: warning: this statement may fall through [-Wimplicit-fallthrough=] div *= 2; ~~~~^~~~ drivers/mfd/db8500-prcmu.c:1595:2: note: here case PRCM_DSI_PLLOUT_SEL_PHI: ^~~~ Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Reviewed-by: Kees Cook <keescook@chromium.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Gustavo A.
