Commit c8602edf3f9471466755329b78d309f2a01dd449

Authored by Thomas Kunze
Committed by Thomas Kunze
1 parent 1d0ad843b0
Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

move drivers/mfd/*.h to include/linux/mfd 

So drivers like collie_battery driver can use
those files easier.
