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.
