[PATCH v2] net: thunderbolt: Fix the parameter passing of tb_xdomain_enable_paths()/tb_xdomain_disable_paths()
Posted by zhangjianrong 3 months, 1 week ago
According to the description of tb_xdomain_enable_paths(), the third
parameter represents the transmit ring and the fifth parameter represents
the receive ring. tb_xdomain_disable_paths() is the same case.

Fixes: ff7cd07f3064 ("net: thunderbolt: Enable DMA paths only after rings are enabled")
