Subject: kernel-doc: fix leading dot in man-mode output
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cdccb316c0860b26ad52f622a7592122a62d02b4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

kernel-doc: fix leading dot in man-mode output

If a parameter description begins with a '.', this indicates a "request"
for "man" mode output (*roff), so it needs special handling.

Problem case is in include/asm-i386/atomic.h for function
atomic_add_unless():
 * @u: ...unless v is equal to u.
This parameter description is currently not printed in man mode output.
