 __devm_regmap_init_slimbus() started to be used instead of __regmap_init_slimbus() after the commit
 mentioned above and turns out the incorrect bus_context pointer (3rd argument) was used in
 __devm_regmap_init_slimbus(). It should be just "slimbus" (which is equal to &slimbus->dev). Correct it.
 The wcd934x codec seems to be the only or the first user of devm_regmap_init_slimbus() but we should fix
 it till the point where __devm_regmap_init_slimbus() was introduced therefore two "Fixes" tags. While at
 this, also correct the same argument in __regmap_init_slimbus(). (CVE-2025-40317)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
