scripts: kernel-doc: fix line number handling
Address several issues related to pointing to the wrong line number: 1) ensure that line numbers will always be initialized When section is the default (Description), the line number is not initializing, producing this: $ ./scripts/kernel-doc --enable-lineno ./drivers/media/v4l2-core/v4l2-mem2mem.c|less **Description** #define LINENO 0 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue Which is not right. Ensure that the line number will always be there. After applied, the result now points to the right location: **Description** #define LINENO 410 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue 2) The line numbers for function prototypes are always + 1, because it is taken at the line after handling the prototype. Change the logic to point to the next line after the /** */ block; 3) The "DOC:" line number should point to the same line as this markup is found, and not to the next one. Probably part of the issues were due to a but that was causing the line number offset to be incremented by one, if --export were used. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
