Subject: [PATCH] net/hns3: fix pointer offset for registers
|
||
|
|
|
||
|
|
[ upstream commit 013fdd2d7b319e6a35d966f375e33ee330d9ccb5 ]
|
||
|
|
|
||
|
|
If the register values of multiple modules are obtained at a time,
|
||
|
|
the register values are incorrect because the data field to be filled
|
||
|
|
pointing to a wrong address. Update the pointer offset of data to
|
||
|
|
get the correct address.
|
||
|
|
|
||
|
|
Fixes: dd4b8bba785f ("net/hns3: support reporting names of registers")
