6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx> [ Upstream commit e4a5e4442a8065c6959e045c061de801d545226d ] Remove the unused phy_delay_nsk variable, before it was wrongly used to compute some register value, the fixed computation is no longer using it and therefore can be removed.
