From d16d9d2ad778e8247617c10703dfd749c776f242 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 12 Aug 2016 21:29:24 +0100 Subject: [PATCH] net: phy: initialize rc to zero to avoid returning garbage value In the case where phydev->interrupts is not PHY_INTERRUPT_ENABLED function vsc85xx_ack_interrupt is returning an uninitialized garbage value. Fix this by initializing rc to zero. Signed-off-by: Colin Ian King Signed-off-by: David S.
