This patch fixes the following warning: drivers/i3c/master/dw-i3c-master.c: In function ‘dw_i3c_master_bus_init’: drivers/i3c/master/dw-i3c-master.c:603:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ret) ^ drivers/i3c/master/dw-i3c-master.c:605:2: note: here case I3C_BUS_MODE_PURE: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
