Technically you are right since the fix is for an old issue that was just
exposed when the driver was enabled by default. But yes, sorry for not
adding that information in the commit message and making it more clear.

Also, I thought that fixes were always a good candidate for the -rc cycle
even if the regression was not introduced during the last merge window.

IOW, it is better to fix issues sooner rather than later.
