Subject: audit: no leading space in audit_log_d_path prefix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c158a35c8a681cf68d36f22f058f9f5466386c71;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

audit: no leading space in audit_log_d_path prefix

audit_log_d_path() injects an additional space before the prefix,
which serves no purpose and doesn't mix well with other audit_log*()
functions that do not sneak extra characters into the log.
