platform/x86: thinkpad_acpi: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/platform/x86/thinkpad_acpi.c: In function ‘thermal_get_sensor’: drivers/platform/x86/thinkpad_acpi.c:6316:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (idx >= 8 && idx <= 15) { ^ drivers/platform/x86/thinkpad_acpi.c:6322:2: note: here case TPACPI_THERMAL_TPEC_8: ^~~~ drivers/platform/x86/thinkpad_acpi.c: In function ‘hotkey_notify’: drivers/platform/x86/thinkpad_acpi.c:4208:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (tp_features.hotkey_wlsw && ^ drivers/platform/x86/thinkpad_acpi.c:4216:3: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comments are modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by:Gustavo A. R. Silva <gustavo@embeddedor.com> Reviewed-by:
