mtd: txx9ndfmc: use devm_request_and_ioremap
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/) // <smpl> @nm@ expression myname; identifier i; @@ struct platform_driver i = { .driver = { .name = myname } }; @@ expression dev,res,size; expression nm.myname; @@ -if (!devm_request_mem_region(dev, res->start, size, - \(res->name\|dev_name(dev)\|myname\))) { - ... - return ...; -} ... when != res->start ( -devm_ioremap(dev,res->start,size) +devm_request_and_ioremap(dev,res) | -devm_ioremap_nocache(dev,res->start,size) +devm_request_and_ioremap(dev,res) ) ... when any when != res->start // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
