This patch fixes the following warnings: drivers/clk/imx/clk-pllv3.c: In function ‘imx_clk_pllv3’: drivers/clk/imx/clk-pllv3.c:446:18: warning: this statement may fall through [-Wimplicit-fallthrough=] pll->div_shift = 1; ~~~~~~~~~~~~~~~^~~ drivers/clk/imx/clk-pllv3.c:447:2: note: here case IMX_PLLV3_USB: ^~~~ drivers/clk/imx/clk-pllv3.c:453:21: warning: this statement may fall through [-Wimplicit-fallthrough=] pll->denom_offset = PLL_IMX7_DENOM_OFFSET; ^ drivers/clk/imx/clk-pllv3.c:454:2: note: here case IMX_PLLV3_AV: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
