I guess you had touched the timestamp of drivers/bluetooth/bt3c_cs.c in
some way without modifying its contents, which made 'git pull' think it is
modified.

The 'git diff' that you did next corrected this behind your back, so that
the subsequent 'git pull' did not see any modification anymore. (BTW, if
you had used 'git status' instead of 'git diff' you would have observed
the same behavior.)
