Merge tag 'clk-microchip-fixes-6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into clk-fixes

Browse Source 
Pull a Microchip clock fix from Claudiu Beznea:

Only one fix for Polarfire SoCs at this time as follows:
- replace devm_kzalloc() with devm_kasprintf(); this has been marked as
  fix to avoid having registered 2 clocks with the same or invalid name in
  case device tree node addresses will be longer such that clocks
  registered with name patern "ccc<node_address>_pll<N>" will exeed the
  allocated space.
