Subject: [PATCH rdma-core 09/13] cxgb4: always query device before
|
|
initializing chip version
|
|
|
|
[ Upstream commit df720f3658ca49aea89cb6e8f11980f30574d10a ]
|
|
|
|
chip_version may be initialized wrongly if alloc_context() is
|
|
invoked multiple times. therefore always query device to derive the
|
|
correct chip_version.
|
|
|
|
Fixes: c7e71b250268 ("cxgb4: fix chipversion initialization")
