When writing a module for testing or debugging purposes, there is no way to
get hold of clk handles. This patch solves this by exposing all valid clocks
as clkdev's for the virtual device tegra-clk-debug.

Are you sure it should be || here, not &&? The following code doesn't seem
to make much sense this way... Perhaps you meant !IS_ERR_OR_NULL(clks[i])?
+ clk_register_clkdev(clks[i], __clk_get_name(clks[i]),
