From mboxrd@z Thu Jan 1 00:00:00 1970 From: t-kristo@ti.com (Tero Kristo) Date: Wed, 2 Jul 2014 11:47:35 +0300 Subject: [PATCH 01/13] ARM: OMAP2+: clock/dpll: fix _dpll_test_fint arithmetics overflow In-Reply-To: <1404290867-6768-1-git-send-email-t-kristo@ti.com> References: <1404290867-6768-1-git-send-email-t-kristo@ti.com> Message-ID: <1404290867-6768-2-git-send-email-t-kristo@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
