Subject: [PATCH] bus: mhi: host: pci_generic: Remove assign resource usage
Date: Wed, 16 Apr 2025 10:49:51 +0530	[thread overview]
Message-ID: <20250416-remove_assin_resource-v1-1-e92dd361fa0a@quicinc.com> (raw)

Avoid redundant usage of pci_assign_resource for BAR allocation.
This is already taken care by PCIe framework. Invocation of this
API leads to unnecessary relocation of BAR space to a new memory
address.
