[PATCH 5.4 213/240] net: bgmac: Fix an erroneous kfree() in bgmac_remove()

From: Greg Kroah-Hartman
Date: Mon Jun 20 2022 - 10:10:35 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit d7dd6eccfbc95ac47a12396f84e7e1b361db654b ]

'bgmac' is part of a managed resource allocated with bgmac_alloc(). It
should not be freed explicitly.

Remove the erroneous kfree() from the .remove() function.

Fixes: 34a5102c3235 ("net: bgmac: allocate struct bgmac just once & don't copy it")
