[PATCH 5.15 058/374] binder: fix comment on binder_alloc_new_buf() return value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Carlos Llamas <cmllamas@xxxxxxxxxx>

commit e1090371e02b601cbfcea175c2a6cc7c955fa830 upstream.

Update the comments of binder_alloc_new_buf() to reflect that the return
value of the function is now ERR_PTR(-errno) on failure.

No functional changes in this patch.
