From 3b8fc902e33e65dd859c0f974c0097b177eeb695 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Mon, 5 Oct 2015 17:56:37 +0300 Subject: [PATCH] ath10k: add a_sle32_to_cpu() Copy a_sle32_to_cpu() from ath6kl so that we can easily handle signed __le32 values. This is needed in struct wmi_pdev_tpc_config_event.
