hwrng: omap - Convert release_resource to release_region/release_mem_region
Request_region should be used with release_region, not release_resource. The local variable mem, storing the result of request_mem_region, is dropped and instead the pointer res is stored in the drvdata field of the platform device. This information is retrieved in omap_rng_remove to release the region. The drvdata field is not used elsewhere. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ ( *x = request_region(...) | *x = request_mem_region(...) ) ... when != release_region(x) when != x = E * release_resource(x); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
