Subject: b43legacy: Do not return TX_BUSY from op_tx
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=664f200610a3c9641ff58fc91b986b804cb1cc2d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

b43legacy: Do not return TX_BUSY from op_tx

Never return TX_BUSY from op_tx. It doesn't make sense to return
TX_BUSY, if we can not transmit the packet.
Drop the packet and return TX_OK.
