VIDEO: Correct use of request_region/request_mem_region
request_region should be used with release_region, not request_mem_region.
Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
the problem is actually the other way around; request_mem_region should be
used instead of request_region.
The semantic patch that finds/fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r1@
expression start;
@@
request_region(start,...)
@b1@
expression r1.start;
@@
request_mem_region(start,...)
@depends on !b1@
expression r1.start;
expression E;
@@
- release_mem_region
+ release_region
(start,E)
// </smpl>
