Subject: [PATCH v4 00/18] staging: r8188eu: Shorten and simplify calls chain
Date: Mon, 13 Sep 2021 20:09:44 +0200	[thread overview]
Message-ID: <20210913181002.16651-1-fmdefrancesco@gmail.com> (raw)

io_ops abstraction is useless in this driver, since there is only one ops
registration. Without io_ops we can get rid of indirect calls mess and
shorten the calls chain.

Shorten the calls chain of rtw_read8/16/32() down to the actual reads.
For this purpose unify the three usb_read8/16/32 into the new
usb_read(); make the latter parameterizable with 'size'; embed most of
the code of usbctrl_vendorreq() into usb_read() and use in it the new
usb_control_msg_recv() API of USB Core.

Shorten the calls chain of rtw_write8/16/32() down to the actual writes.
For this purpose unify the four usb_write8/16/32/N() into the new
usb_write(); make the latter parameterizable with 'size'; embed most of
the code of usbctrl_vendorreq() into usb_write() and use in it the new
usb_control_msg_send() API of USB Core.

The code with the modifications was thoroughly tested by Pavel Skripkin
using a TP-Link TL-WN722N v2 / v3 [Realtek RTL8188EUS] and by Fabio M.
De Francesco using a ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano].
