Hi all,
After merging the nand tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
drivers/mtd/nand/raw/ingenic/jz4725b_bch.c: In function 'jz4725b_bch_read_parity':
drivers/mtd/nand/raw/ingenic/jz4725b_bch.c:147:12: warning: this statement may fall through [-Wimplicit-fallthrough=]
dest8[2] = (val >> 16) & 0xff;
~~~~~~~~~^~~~~~~~~~~~~~~~~~~~
drivers/mtd/nand/raw/ingenic/jz4725b_bch.c:148:2: note: here
case 2: /* fall-through */
^~~~
drivers/mtd/nand/raw/ingenic/jz4725b_bch.c:149:12: warning: this statement may fall through [-Wimplicit-fallthrough=]
dest8[1] = (val >> 8) & 0xff;
~~~~~~~~~^~~~~~~~~~~~~~~~~~~
drivers/mtd/nand/raw/ingenic/jz4725b_bch.c:150:2: note: here
case 1: /* fall-through */
^~~~
Introduced by commit
acb29396f956 ("mtd: rawnand: ingenic: Add support for the JZ4725B")
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 (i.e. before the next case label).
