Subject: [PATCH RFC v1 3/7] rtw88: Use rtw_iterate_stas where the iterator reads or writes registers
Date: Sat, 17 Jul 2021 22:40:53 +0200 [thread overview]
Message-ID: <20210717204057.67495-4-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20210717204057.67495-1-martin.blumenstingl@googlemail.com>
Upcoming SDIO support may sleep in the read/write handlers. Switch
all users of rtw_iterate_stas_atomic() which are either reading or
writing a register to rtw_iterate_stas().
