The clk_disable() in the common clock framework (drivers/clk/clk.c)
returns immediately if a given clk is NULL or an error pointer. It
allows clock consumers to call clk_disable() without IS_ERR_OR_NULL
checking if drivers are only used with the common clock framework.
Unfortunately, NULL/error c

My datasheet says to wait at least 5ms before re-enabling the clock

Ah, found it in the core. It is doing it for 10ms. Maybe my search
pattern was not fuzzy enough ;)

This patch fixes an issue that usbhsg_queue_done() may cause kernel
panic when dma callback is running and usb_ep_disable() is called
by interrupt handler. (Especially, we can reproduce this issue using
g_audio with usb-dmac driver.)
For example of a flow:
usbhsf_dma_complete (on tasklet)
