Hi Team,

Android Kernel Booting is stopped for IMX8MEVK Board at "crg random init done".

Any suggestion to proceed.

Thanks& Regards,

Hello himabindu,

This change inadvertently impacts urandom_read, causing the crng_init==1 state to be treated as uninitialized and causing urandom to block, despite this state existing specifically to support non-cryptographic needs at boot time: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/char/random.c#n1863
