Date: Tue, 27 Oct 2020 23:54:48 +0100 Message-Id: <20201027225454.3492351-10-bigeasy@linutronix.de> In-Reply-To: <20201027225454.3492351-1-bigeasy@linutronix.de> References: <20201027225454.3492351-1-bigeasy@linutronix.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-wireless@vger.kernel.org hostap_get_wireless_stats() is the iw_handler_if::get_wireless_stats() callback of this driver. This callback was not allowed to sleep until commit a160ee69c6a46 ("wext: let get_wireless_stats() sleep") in v2.6.32. Remove the therefore pointless in_atomic() check.
