X-Git-Tag: v6.15-rc1~214^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5bebe2e4fe27bf68b4993d62be2f8bae9e6229d6;p=thirdparty%2Flinux.git

x86/boot: Change some static bootflag functions to bool

The return values of some functions are of boolean type. Change the
type of these function to bool and adjust their return values.

No functional change intended.
