It doesn't change any single patch (or order), it only renames files. This creates some place for more backports, as we were already using 398 prefix which left only 1 slot.

Subject: [PATCH] brcmfmac: avoid runtime-pm for sdio host controller
|
|
|
|
Several host controllers supporting runtime-pm are causing issues
|
|
with our sdio wireless cards because they disable the sdio interrupt
|
|
upon going into runtime suspend. This patch avoids that by doing
|
|
a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
|
|
Duo 13 which uses sdhci-acpi host controller.
