[PATCH net-next] net: libwx: fix an error code in wx_alloc_page_pool()

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

 



This function always returns success.  We need to preserve the error
code before setting rx_ring->page_pool = NULL.

Fixes: 850b971110b2 ("net: libwx: Allocate Rx and Tx resources")

Applies to net-next.
