Subject: [PATCH v2 0/6] USB: serial: use wrappers for usb_control_msg()
Date: Mon,  2 Aug 2021 02:01:16 +0530	[thread overview]
Message-ID: <20210801203122.3515-1-himadrispandya@gmail.com> (raw)

There are many usages of usb_control_msg() that can use the new wrapper
functions usb_contro_msg_send() & usb_control_msg_recv() for better
error checks on short reads and writes. They can also be used to avoid
allocating redundant dma buffers that are generally required to use
usb_control_msg(). Hence use them whenever possible and avoid using
usb_control_msg() directly.

Changes in v2:
 - Drop unnecessary use of wrappers
 - Drop unrelated style changes

Additional Info:
- This is a super late follow-up on v1 that was submitted a while
ago(my sincere apologies). (All patches are rebased and
compile tested.)
- v1 patches: https://lkml.org/lkml/2020/11/4/40
- Patches that introduced the wrapper functions:
