Subject: dm vdo: use get_random_u32() where appropriate
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=758a43cd4e7907513505eebb6c266d8ab84f9e96;p=thirdparty%2Flinux.git

dm vdo: use get_random_u32() where appropriate

Use the typed random integer helpers instead of
get_random_bytes() when filling a single integer variable.
The helpers return the value directly, require no pointer
or size argument, and better express intent.
