Subject: [PATCH] i2c: mlxcpld: Fix criteria for frequency setting
Git-commit: 52f57396c75acd77ebcdf3d20aed24ed248e9f79
Patch-mainline: v5.15-rc5
References: git-fixes stable-5.14.12
Value for getting frequency capability wrongly has been taken from
register offset instead of register value.
Fixes: 66b0c2846ba8 ("i2c: mlxcpld: Add support for I2C bus frequency setting")
