Henry Martin 0a2712cd24 clk: bcm: rpi: Add NULL check in raspberrypi_clk_register() ...

[ Upstream commit 73c46d9a93 ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
raspberrypi_clk_register() does not check for this case, which results
in a NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.
