[PATCH 1/4] accel/rocket: Fix the IOMMU domain leak in rocket_ioctl_create_bo

[Chaoyi Chen]

From: Chaoyi Chen <chaoyi.chen at rock-chips.com>

When rocket_ioctl_create_bo fails, rocket_iommu_domain_put should be
called to avoid an IOMMU domain leak.

Fixes: 658ebeac3351 ("accel/rocket: Add IOCTL for BO creation")
