Mainline patch information (included in 6.18-rc): mfd: kempld: Switch back to earlier ->init() behavior Commit 309e65d151ab9be1e7b01d822880cd8c4e611dff
Please consider this patch for all supported stable and longterm versions that include the faulty commit 9e36775c22c7 mentioned in the patch description. This includes all Kernel versions starting with v6.10.
Newer Kontron/JUMPtec products are not listed in the kempld drivers DMI table, as they are supposed to be identified using ACPI. Without this patch there is no way to get the driver working with those boards on the affected kernel versions.
Thanks in advance, Michael Brunner
