[PATCH v2 4.4] net: cdc_ncm: initialize drvflags before usage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matthias Hintzmann <matthias.dev@xxxxxx>

ctx->drvflags is checked in the if clause before beeing initialized. 
Move initialization before first usage.

Note, that the if clause was backported with commit 75f82a703b30 
("cdc_ncm: Set NTB format again after altsetting switch for Huawei 
devices") from mainline (upstream commit 2b02c20ce0c2 ("cdc_ncm: Set 
NTB format again after altsetting switch for Huawei devices"). 
In mainline, the initialization is at the right place before the if 
clause.

Fixes: 75f82a703b30 ("cdc_ncm: Set NTB format again after altsetting switch for Huawei devices")
