Date: Mon, 18 Sep 2017 10:04:20 +0200 From: Antoine Tenart <antoine.tenart@...e-electrons.com> To: kishon@...com Cc: Antoine Tenart <antoine.tenart@...e-electrons.com>, gregory.clement@...e-electrons.com, thomas.petazzoni@...e-electrons.com, miquel.raynal@...e-electrons.com, nadavh@...vell.com, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/3] phy: mvebu-cp110-comphy: fix mux error check The mux value is retrieved from the mvebu_comphy_get_mux() function which returns an int. In mvebu_comphy_power_on() this int is stored to a u32 and a check is made to ensure it's not negative. Which is wrong. This fixes it.
