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: https://lkml.org/lkml/2020/9/14/859 Himadri Pandya (6): USB: serial: ch314: use usb_control_msg_recv() and usb_control_msg_send() USB: serial: cp210x: use usb_control_msg_recv() and usb_control_msg_send() USB: serial: f81232: use usb_control_msg_recv() and usb_control_msg_send() USB: serial: ftdi_sio: use usb_control_msg_recv() USB: serial: keyspan_pda: use usb_control_msg_recv() USB: serial: kl5kusb105: use usb_control_msg_recv() and usb_control_msg_send() drivers/usb/serial/ch341.c | 97 +++++++++------------------- drivers/usb/serial/cp210x.c | 107 +++++++++---------------------- drivers/usb/serial/f81232.c | 96 ++++++++++----------------- drivers/usb/serial/ftdi_sio.c | 53 +++++---------- drivers/usb/serial/keyspan_pda.c | 70 +++++++++----------- drivers/usb/serial/kl5kusb105.c | 79 ++++++++++------------- 6 files changed, 173 insertions(+), 329 deletions(-) -- 2.17.1
