Description OSIDB Bzimport 2026-04-22 15:07:42 UTC 
In the Linux kernel, the following vulnerability has been resolved:

dmaengine: xilinx: xdma: Fix regmap init error handling

devm_regmap_init_mmio returns an ERR_PTR() upon error, not NULL.
Fix the error check and also fix the error message. Use the error code
from ERR_PTR() instead of the wrong value in ret.
