KASAN reports an out-of-bound access to raspberrypi_clk_variants[]:

==================================================================
BUG: KASAN: global-out-of-bounds in raspberrypi_clk_probe+0x1dc/0x690
Read of size 1 at addr ffffcc7116d615a0 by task kworker/u8:0/8

CPU: 1 PID: 8 Comm: kworker/u8:0 Not tainted 6.0.0-rc3-00900-g08f4df4a3c53 raspberrypi#10

this kernel is a little bit older and doesn't contain bc163555603e ("clk: bcm: rpi: Prevent out-of-bounds access").

Can you please check Linux 6.0?

Best regards
