Re: [PATCH v6] mwifiex: parse device tree node for PCIe

From: Xinming Hu <redacted>

This patch derives device tree node from pcie bus layer framework, and
fixes a minor memory leak in mwifiex_pcie_probe() (in failure path).
Device tree bindings file has been renamed(marvell-sd8xxx.txt ->
marvell-8xxx.txt) to accommodate PCIe changes.

v2: Included vendor and product IDs in compatible strings for PCIe
chipsets(Rob Herring)
v3: Patch is created using -M option so that it will only include diff of
original and renamed files(Rob Herring)
Resend v3: Resending the patch because I missed to include device tree mailing
while sending v3.
v4: Fix error handling, also move-on even if no device tree node is present.
v5: Update commit log to include memory leak, return -EINVAL instead of -1.
v6: Remove an unnecessary error print, fix typo in commit log
