[PATCH 0/7] replace devm_request_and_ioremap by devm_ioremap_resource

From: Julia Lawall <hidden>
Date: 2013-08-19 11:21:09 

devm_request_and_ioremap has been replaced by devm_ioremap_resource, which
gives more informative error return code information.  This patch series
removes the remaining uses of devm_request_and_ioremap.

This patch series was generated using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci from the Linux kernel
source tree.  Manual modifications have been made to move associated calls
to platform_get_resource closer to the resulting call to
devm_ioremap_resource and to remove the associated error handling code.

[PATCH 6/7] video: xilinxfb: replace devm_request_and_ioremap by devm_ioremap_resource

From: Julia Lawall <hidden>
Date: 2013-08-19 11:21:08 

From: Julia Lawall <redacted>

Use devm_ioremap_resource instead of devm_request_and_ioremap.

This was done using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci

The initialization of drvdata->regs_phys was manually moved lower, to take
advantage of the NULL test on res performed by devm_ioremap_resource.
