Subject: [PATCH] net: hamradio: baycom_epp: Mark expected switch fall-through
Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: i386):
drivers/net/hamradio/baycom_epp.c: In function ‘transmit’:
drivers/net/hamradio/baycom_epp.c:491:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (i) {
^
drivers/net/hamradio/baycom_epp.c:504:3: note: here
default: /* fall through */
^~~~~~~
Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
