From 6340c8720ce34f35b41a2e15d69fe3d755cb2104 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Wed, 2 Jul 2014 11:47:35 +0300 Subject: [PATCH] ARM: OMAP2+: clock/dpll: fix _dpll_test_fint arithmetics overflow The divider value provided to the _dpll_test_fint can reach value of 256 with J type DPLLs (USB etc.), which causes an overflow with the u8 datatype. Fix this by changing the parameter to be an int instead.
