[ Upstream commit 7d2c6b1edf790d96e9017a0b27be2425e1af1532 ]
Changeset 6b80975c6308 ("scripts: kernel-doc: fix typedef parsing") added support for things like:
typedef unsigned long foo();
However, it caused a regression on this prototype:
typedef bool v4l2_check_dv_timings_fnc(const struct v4l2_dv_timings *t, void *handle);
This is only noticed after adding a patch that checks if the kernel-doc identifier matches the typedef:
./scripts/kernel-doc -none $(git grep '^.. kernel-doc::' Documentation/ |cut -d ' ' -f 3|sort|uniq) 2>&1|grep expecting include/media/v4l2-dv-timings.h:38: warning: expecting prototype for typedef v4l2_check_dv_timings_fnc. Prototype was for typedef nc instead
The problem is that, with the new parsing logic, it is not checking for complete words at the type part.
Fix it by adding a \b at the end of each type word at the regex.
