Use of return codes than assert

[pranjalchanda08]

Describe the bug In many cases the driver automatically panics and does not let the user act upon the error cases in a dynamic environment. It is better to:

• Use return codes instead of asserts and let the user decide what to perform with the returned code.
• Use positive error codes to accommodate 0x0000 to 0xffff error codes.
