From c094ba34b8f780885d029ce3c2715a194b780e5d Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Wed, 15 Apr 2009 10:44:52 -0700 Subject: [PATCH] ARM: OMAP2: possible division by 0 In linus' git tree the functions can be found at: vi arch/arm/mach-omap2/usb-tusb6010.c +200 - tusb6010_platform_retime() vi arch/arm/mach-omap2/gpmc.c +94 - gpmc_get_fclk_period() vi arch/arm/mach-omap2/usb-tusb6010.c +53 - tusb_set_async_mode() vi arch/arm/mach-omap2/usb-tusb6010.c +111 - tusb_set_sync_mode() is -ENODEV appropriate when sysclk_ps == 0? This was found by code analysis, please review. ------------------------------>8-------------8<--------------------------------- gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it seems. In tusb_set_sync_mode() this may result in a division by zero.
