mtd: txx9ndfmc: use devm_request_and_ioremap
Author: Julia Lawall <julia@diku.dk> Reimplement a call to devm_request_mem_region followed by a call to ioremap or ioremap_nocache by a call to devm_request_and_ioremap. The semantic patch that makes this transformation is as follows: (http://coccinelle.lip6.fr/) // @nm@ expression myname; identifier i; @@ struct platform_driver i = { .driver = { .name = myname } }; @@ expression …

mtd: lantiq-flash: drop iounmap for devm_ allocated data
Author: Julia Lawall <julia@diku.dk> Data allocated with devm_ioremap or devm_ioremap_nocache should not be freed using iounmap, because doing so causes a dangling pointer, and a subsequent double free. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r@ expression x; @@ ( x = devm_ioremap(…) | x = devm_ioremap_nocache(…) ) @@ expression …
