[PATCH 2/5] mfd: tps65910: move interrupt implementation code to mfd file
From: Laxman Dewangan
Date: Tue Oct 09 2012 - 08:02:57 EST
In place of implementing the irq support in separate file,
moving implementation to main mfd file.
The irq files only contains the table and init steps only
and does not need extra file to have this only for this
purpose.
