| |
Hi all,
After merging the input-current tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/input/mouse/elantech.c: In function 'elantech_use_host_notify': drivers/input/mouse/elantech.c:1843:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (dmi_get_bios_year() >= 2018) ^ drivers/input/mouse/elantech.c:1845:2: note: here default: ^~~~~~~
Introduced by commit
883a2a80f79c ("Input: elantech - enable SMBus on new (2018+) systems")
I get these warnings 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).
