linux-next: build warning after merge of the clk tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the clk tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

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:
  ^~~~

Introduced by commit

  01d0a541ff4b ("clk: imx: correct i.MX7D AV PLL num/denom offset")

I get this warning because I am building with -Wimplicit-fallthrough
in attempt to catch new additions early.  The gcc warning can be turned
off by adding a /* fall through */ comment at the point the fall through
happens (assuming that the fall through is intentional).
