Roel Kluin d94a2eddf5 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.
