[PATCH 6.0 585/862] phy: qcom-qmp-pcie: fix resource mapping for SDM845 QHP PHY

[Greg Kroah-Hartman]

From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>

[ Upstream commit 0a40891b83f257b25a2b983758f72f6813f361cb ]

On SDM845 one of PCIe PHYs (the QHP one) has the same region for TX and
RX registers. Since the commit 4be26f695ffa ("phy: qcom-qmp-pcie: fix
memleak on probe deferral") added checking that resources are not
allocated beforehand, this PHY can not be probed anymore. Fix this by
skipping the map of ->rx resource on the QHP PHY and assign it manually.

Fixes: 4be26f695ffa ("phy: qcom-qmp-pcie: fix memleak on probe deferral")
