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.
