Subject: staging: speakup: i18n.c: Change return type from int to bool
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eaeab71f27c485e8940782304158f41c3fff7139;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: speakup: i18n.c: Change return type from int to bool

The possible return values (0 or 1) for compare_specifiers
and fmt_validate represent whether a condition holds or not, so
conceptually, they are booleans.

Update documentation for these two functions.

Change type of variable 'still_comparing' from int to bool too,
inside fmt_validate, because it is intended to hold truth values
as well.
