Date: Tue, 8 Apr 2014 14:33:04 +0200 From: Jean Delvare <jdelvare@...e.de> To: linux-kernel@...r.kernel.org Cc: Matt Mackall <mpm@...enic.com>, Herbert Xu <herbert@...dor.apana.org.au>, Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCH 2/3] hw_random: Turn HW_RANDOM into a menuconfig This makes configuration more convenient IMHO, and avoids having to repeat the dependency on HW_RANDOM for every single driver.
