Subject: [PATCH v3 2/6] staging: r8188eu: add helper macro for printing registers
Date: Tue, 24 Aug 2021 10:27:20 +0300	[thread overview]
Message-ID: <84e388b0eaaf3c56f575216b0571318ed799a4d2.1629789580.git.paskripkin@gmail.com> (raw)
In-Reply-To: <cover.1629789580.git.paskripkin@gmail.com>

There are a lof of places, where DBG_88E() is used to print register
value. Since following patches change _rtw_read*() family
prototypes, we can wrap printing registers into useful macro to avoid
open-coding error checking like this:

	u32 tmp;
	if (!rtw_read(&tmp))
		DBG("reg = %d\n", tmp);

So, added DBG_88E_REG{8,16,32} macros for printing register values.
