linux-stable.git/drivers/net/usb, branch v4.9.64 Linux kernel stable tree cdc_ncm: Set NTB format again after altsetting switch for Huawei devices 2017-11-15T14:53:17+00:00 Enrico Mioso mrkiko.rs@gmail.com 2017-07-11T15:21:52+00:00 bddc61e7732be12d2f09391a2434253d9cb34f52 commit 2b02c20ce0c28974b44e69a2e2f5ddc6a470ad6f upstream. Some firmwares in Huawei E3372H devices have been observed to switch back to NTB 32-bit format after altsetting switch. This patch implements a driver flag to check for the device settings and set NTB format to 16-bit again if needed. The flag has been activated for devices controlled by the huawei_cdc_ncm.c driver. V1->V2: - fixed broken error checks - some corrections to the commit message V2->V3: - variable name changes, to clarify what's happening - check (and possibly set) the NTB format later in the common bind code path Signed-off-by: Enrico Mioso <mrkiko.rs@gmail.com> Reported-and-tested-by: Christian Panton <christian@panton.org> Reviewed-by: Bjørn Mork <bjorn@mork.no> CC: Bjørn Mork <bjorn@mork.no> CC: Christian Panton <christian@panton.org> CC: linux-usb@vger.kernel.org CC: netdev@vger.kernel.org CC: Oliver Neukum <oliver@neukum.org> Signed-off-by: David S.

commit 2b02c20ce0c28974b44e69a2e2f5ddc6a470ad6f upstream.

Some firmwares in Huawei E3372H devices have been observed to switch back
to NTB 32-bit format after altsetting switch.
This patch implements a driver flag to check for the device settings and
set NTB format to 16-bit again if needed.
The flag has been activated for devices controlled by the huawei_cdc_ncm.c
driver.

V1->V2:
- fixed broken error checks
- some corrections to the commit message
V2->V3:
- variable name changes, to clarify what's happening
- check (and possibly set) the NTB format later in the common bind code path
