drivers/vlynq/vlynq.c: fix resource size off by 1 error
In this case, the calls to request_mem_region, ioremap, and
release_mem_region all have a consistent length argument, len, but since
in other files (res->end - res->start) + 1, equivalent to
resource_size(res), is used for a resource-typed structure res, one could
consider whether the same should be done here.
The problem was found using the following semantic patch:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
struct resource *res;
@@
- (res->end - res->start) + 1
+ resource_size(res)
@@
struct resource *res;
@@
- res->end - res->start
+ BAD(resource_size(res))
// </smpl>
