We have been getting build warning about: drivers/char/hw_random/stm32-rng.c: In function 'stm32_rng_read': drivers/char/hw_random/stm32-rng.c:82:19: warning: 'sr' may be used uninitialized in this function On checking the code it turns out that sr can never be used uninitialized as sr is getting initialized in the while loop and while loop will always execute as the minimum value of max can be 32. So just initialize sr to 0 while declaring it to silence the compiler.
