From 8eb2ffbf7be94c546a873540ff952140465125e5 Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Mon, 15 Oct 2012 23:43:29 +0200 Subject: [PATCH 1/1] random: fix debug format strings MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fix the following warnings in formatting debug output: drivers/char/random.c: In function ‘xfer_secondary_pool’: drivers/char/random.c:827: warning: format ‘%d’ expects type ‘int’, but argument 7 has type ‘size_t’ drivers/char/random.c: In function ‘account’: drivers/char/random.c:859: warning: format ‘%d’ expects type ‘int’, but argument 5 has type ‘size_t’ drivers/char/random.c:881: warning: format ‘%d’ expects type ‘int’, but argument 5 has type ‘size_t’ drivers/char/random.c: In function ‘random_read’: drivers/char/random.c:1141: warning: format ‘%d’ expects type ‘int’, but argument 5 has type ‘ssize_t’ drivers/char/random.c:1145: warning: format ‘%d’ expects type ‘int’, but argument 5 has type ‘ssize_t’ drivers/char/random.c:1145: warning: format ‘%d’ expects type ‘int’, but argument 6 has type ‘long unsigned int’ by using '%zd' instead of '%d' to properly denote ssize_t/size_t conversion.
