Subject: [PATCH 06/21] binder: fix comment on binder_alloc_new_buf() return value
Date: Thu, 2 Nov 2023 18:59:07 +0000 [thread overview]
Message-ID: <20231102185934.773885-7-cmllamas@google.com> (raw)
In-Reply-To: <20231102185934.773885-1-cmllamas@google.com>
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.
Cc: stable@vger.kernel.org
Fixes: 57ada2fb2250 ("binder: add log information for binder transaction failures")
