[PATCH 1/2] mfd: omap-usb-tll: annotate struct usbtll_omap with __counted_by

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use the __counted_by compiler attribute for the "struct clk *ch_clk[]"
flexible array member to improve the results of array bound sanitizers.

The comments for the variables are no longer needed as it is now clear
what is what.
