In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/mfd/mxs-lradc.c: In function ‘mxs_lradc_probe’: drivers/mfd/mxs-lradc.c:179:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (lradc->soc == IMX28_LRADC) { ^ drivers/mfd/mxs-lradc.c:185:3: 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.
