[PATCH v2 0/7] hwrng: Add support for STMicroelectronics' RNG IP

v1 => v2:
 - New patch: Also fixing /dev/hw_random => /dev/hwrng in Kconfig
 - Fix 2099 => 2009 typo in commit log
 - Fix 'number of random numbers sourced' return value
 - Treat devm_clk_get()'s return value correctly
 - Check return value of clk_prepare_enable()
 - Use sysfs_streq() instead of manually stripping '\n' from sysfs

The main aim of this set is to allow users to access ST's hardware
random number generator.  It's a simple device, which only requires
a simple driver.

We're also taking the liberty to update some out of date HWRNG
documentation and making the sysfs interface a little easier to
use by ignoring any '\n' which may have been inadvertently passed.
