Subject: [PATCH net-next 06/18] can: tcan4x5x: get rid of false clock errors

From: Sean Nyekjaer <sean@...nix.com>

tcan4x5x devices only requires the clock "cclk", so call
devm_clk_get() directly. This is done to avoid
m_can_class_get_clocks() that checks for both hclk and cclk and
results in this warning message:

| tcan4x5x spi0.0: no clock found
