omap-rng: Change RNG_CONFIG_REG to RNG_CONTROL_REG in init
PATCH v2 1/1 omap-rng: Change RNG_CONFIG_REG to RNG_CONTROL_REG in init
omap4_rng_init() checks bit 10 of the RNG_CONFIG_REG to determine whether the RNG is already running before performing any initiliasation. This is not the correct register to check, as the enable bit is in RNG_CONFIG_CONTROL. Read from RNG_CONTROL_REG instead.
