Date: Tue, 15 Jul 2014 20:00:53 +0300 From: Sam Asadi <asadi.samuel@...il.com> To: gregkh@...uxfoundation.org Cc: devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, Tero Kristo <t-kristo@...com>, Paul Walmsley <paul@...an.com>, sam-the-6 <asadi.samuel@...il.com> Subject: [PATCH 38/94] ARM: OMAP2+: clock/dpll: fix _dpll_test_fint arithmetics overflow From: Tero Kristo <t-kristo@...com> 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.
