From ed424bb3680b6e6167a44c5c195ec8f9aea3ab3b Mon Sep 17 00:00:00 2001 From: PrasannaKumar Muralidharan Date: Fri, 18 Nov 2016 23:00:10 +0530 Subject: hwrng: Make explicit that max >= 32 always As hw_random core calls ->read with max > 32 or more, make it explicit. Also remove checks involving 'max' being less than 8.
