Subject: [PATCH 1/2] staging: r8188eu: ctrl vendor req value is always 0x05
Date: Wed, 18 Aug 2021 22:00:40 +0200	[thread overview]
Message-ID: <20210818200041.10870-1-martin@kaiser.cx> (raw)

The bRequest value for the vendor specific control requests sent by this
driver is always 0x05. Replace the function parameter with the define from
usb_ops.h.

This patch is an adaptation of commit eeb4661560ff ("staging: rtl8188eu:
ctrl vendor req value is always 0x05") for the new r8188eu driver.

Signed-off-by: Martin Kaiser <martin@kaiser.cx>
