Subject: [PATCH rdma-core 09/13] cxgb4: always query device before
|
|
|
baba1b |
initializing chip version
|

[ Upstream commit df720f3658ca49aea89cb6e8f11980f30574d10a ]
|
|
|
baba1b |
|
|
|
baba1b |
chip_version may be initialized wrongly if alloc_context() is
|
|
|
baba1b |
invoked multiple times. therefore always query device to derive the
|
|
|
baba1b |
correct chip_version.
