The patch titled
m41t00: fix bitmasks when writing to chip
has been removed from the -mm tree. Its filename is
m41t00-fix-bitmasks-when-writing-to-chip.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: David Barksdale <amatus@xxxxxxxxxx>
Fix the bitmasks used when writing to the M41T00 registers. The original
code used a mask of 0x7f when writing to each register, this is incorrect
and probably the result of a copy-paste error. As a result years from 1980
to 1999 will be read back as 2000 to 2019.
