Subject: [PATCH v2] staging: r8188eu: remove rtw_usleep_os
Date: Sun, 26 Jun 2022 20:06:03 +0200	[thread overview]
Message-ID: <20220626180603.287054-1-martin@kaiser.cx> (raw)
In-Reply-To: <20220602194807.281115-1-martin@kaiser.cx>

Remove the rtw_usleep_os helper function. There are only two callers, both
of which call rtw_usleep_os(100). This is equivalent to msleep(1).

Signed-off-by: Martin Kaiser <martin@kaiser.cx>
---
changes in v2:
- use msleep(1) instead of usleep_range
