Merge tag 'clk-microchip-fixes-6.1-2' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into clk-microchip
Pull Microchip clk driver updates from Claudiu Beznea:
It contains a fix for Microchip Polarfire clocks; the fix consist in checking
the return value of devm_kzalloc() in mpfs_ccc_register_outputs() to
avoid possible null pointer dereference.
