2013-05-12drivers/char/hw_random: don't check resource with devm_ioremap_resourceWolfram Sang
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-03-22hwrng: mxc-rnga - Use devm_ioremap_resource()Fabio Estevam
Using devm_ioremap_resource() can make the code cleaner and simpler. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2013-03-15drivers: char: use module_platform_driver_probe()Fabio Porcedda
This patch converts the drivers to use the module_platform_driver_probe() macro which makes the code smaller and a bit simpler.

2012-09-07hwrng: mxc-rnga - Access data via structureFabio Estevam
In current driver, everytime we need to access the rng clock ,ie to enable or disable it, a call to clk_get is done. This is not correct and the preferred way is to provide a rng data structure that could be used for accessing rng resources.
