[PATCH 4.9 005/121] mtd: Fix comparison in map_word_andequal()

[Greg Kroah-Hartman]

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

commit ea739a287f4f16d6250bea779a1026ead79695f2 upstream.

Commit 9e343e87d2c4 ("mtd: cfi: convert inline functions to macros")
changed map_word_andequal() into a macro, but also changed the right
hand side of the comparison from val3 to val2.  Change it back to use
val3 on the right hand side.

Thankfully this did not cause a regression because all callers
currently pass the same argument for val2 and val3.
