| |
Hi Bartlomiej,
After merging the fbdev tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/video/fbdev/sm712fb.c: In function 'smtc_blank': drivers/video/fbdev/sm712fb.c:900:4: warning: this statement may fall through [-Wimplicit-fallthrough=] smtc_seqw(0x6b, 0x02); ^~~~~~~~~~~~~~~~~~~~~ drivers/video/fbdev/sm712fb.c:901:3: note: here case 0x720: ^~~~
Introduced by commit
f627caf55b8e ("fbdev: sm712fb: fix crashes and garbled display during DPMS modesetting")
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).
