[PATCH RFC 1/5] pinctrl: mvebu: constify mvebu_mpp_ctrl structures
Russell King
rmk+kernel at armlinux.org.uk
Fri Jan 13 03:03:15 PST 2017
As the mvebu_mpp_ctrl structures contain function pointers, it is
preferable for these to be made read-only to prevent the function
pointers being modified. So make these const.
