In 2019, we introduced pin_user_pages*() and now we are converting

When pin_user_pages() returns numbers of partially mapped pages,
those pages were not unpinned as part of error handling. Fixed
it as part of this patch.
Hi Souptick,
btw, Bharath (+cc) attempted to do the "put" side of this, last year.
That got as far as a v4 patch [1], and then I asked him to let me put
it into my tree. But then it didn't directly apply anymore after the
whole design moved to pin+unpin, and so here we are now.
If Bharath is still doing kernel work, you might offer him a Co-Developed-by:
tag (see https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html).
Sure, will add him as *Co-Developed-by*
Yes, but it's best to wait and see if he responds, before adding that tag, because
it also required a Signed-off-by from him.
thanks,
