Commit b8ac9fc0e8cda9f9776019c5b0464b0c6d2d4c90

Authored by Stephen Rothwell
Committed by Greg Kroah-Hartman
1 parent a2ab3d3000
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

uio: make uio_info's name and version const 

These are only ever assigned constant strings and never modified.

This was noticed because Wolfram Sang needed to cast the result of
of_get_property() in order to assign it to the name field of a struct
uio_info.
