This patch fixes the following warnings: drivers/clk/samsung/clk-s3c2443.c: In function ‘s3c2443_common_clk_init’: drivers/clk/samsung/clk-s3c2443.c:390:3: warning: this statement may fall through [-Wimplicit-fallthrough=] samsung_clk_register_alias(ctx, s3c2450_aliases, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ARRAY_SIZE(s3c2450_aliases)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/clk/samsung/clk-s3c2443.c:393:2: note: here case S3C2416: ^~~~ 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.
