CVE-2026-74380

In the Linux kernel, the following vulnerability has been resolved:

gpu: host1x: Fix iommumapsgtable() return value check

Commit "iommu: return full error code from iommumapsg_atomic" changed iommumapsgtable() to return an ssizet and negative values in error cases, rather than a sizet and a zero.

pin_job() also was incorrectly assigning to 'int', which could cause overflows into negative values.

Update pinjob() to correctly check for errors from iommumap_sgtable.
