libavb: Fix build warnings after updating the lib
After updating libavb to most recent version from AOSP/master, two new
warnings appear:
Warning #1:
lib/libavb/avb_cmdline.c: In function 'avb_append_options':
lib/libavb/avb_cmdline.c:365:15: warning: 'dm_verity_mode' may be
used uninitialized in this function
[-Wmaybe-uninitialized]
new_ret = avb_replace(
^~~~~~~~~~~~
slot_data->cmdline, "$(ANDROID_VERITY_MODE)", dm_verity_mode);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/libavb/avb_cmdline.c:374:8: warning: 'verity_mode' may be used
uninitialized in this function
[-Wmaybe-uninitialized]
if (!cmdline_append_option(
^~~~~~~~~~~~~~~~~~~~~~
slot_data, "androidboot.veritymode", verity_mode)) {
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Warning #2:
lib/libavb/avb_slot_verify.c: In function 'avb_slot_verify':
lib/libavb/avb_slot_verify.c:1349:23: warning: 'ret' may be used
uninitialized in this function
[-Wmaybe-uninitialized]
AvbSlotVerifyResult ret;
^~~
Fix those by providing default return values to affected functions.
