I used the words which Chris sent:

: Make it possibile to get test results via sysfs.  It helps to do tests
: non-interactively.
: 
: We have the file created under sysfs already and we could use it to out test
: results.
: 
: Prior to this patch, the "test" file under each card's sysfs node was
: write-only, and results were obtained by looking at dmesg.  This patch
: improves programmatic access to the test results, making them available by
: reading back from the same "test" file:
: 
: [root@...t mmc0:e624]# echo 6 > test
: [root@...t mmc0:e624]# cat test
: Test 6: 2

which is good enough.  You can send me replacement changelog text any
old time - it's not problem.  I'm forever editing changelogs, mainly
adding acked-by's etc.
