From: Stephen Boyd Date: Thu, 10 May 2012 12:51:30 +0000 (+0000) Subject: ks8851: Update link status during link change interrupt X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=062e55e3960062fc2fb62a7274b4c253003eba73;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ks8851: Update link status during link change interrupt If a link change interrupt comes in we just clear the interrupt and continue along without notifying the upper networking layers that the link has changed. Use the mii_check_link() function to update the link status whenever a link change interrupt occurs. Cc: Ben Dooks Signed-off-by: Stephen Boyd Signed-off-by: David S.
