wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when executing brcms_up. But brcms_up is called from brcms_ops_start while the latter holds a spin lock. Thus, we cannot use usleep_range but have to use udelay. This fixes: BUG: scheduling while atomic: NetworkManager/1652/0x00000200 [...] Call Trace: [<ffffffff81582522>] __schedule_bug+0x48/0x54 [<ffffffff815892b6>] __schedule+0x596/0x6d0 [<ffffffff81589719>] schedule+0x29/0x70 [<ffffffff8158893c>] schedule_hrtimeout_range_clock+0xfc/0x140 [<ffffffff81060f10>] ? update_rmtp+0x70/0x70 [<ffffffff81588993>] schedule_hrtimeout_range+0x13/0x20 [<ffffffff810495e0>] usleep_range+0x40/0x50 [<ffffffffa05dedcb>] wlc_lcnphy_rx_iq_cal.constprop.10+0x59b/0xa90 [brcmsmac] [<ffffffffa05df4ce>] wlc_lcnphy_periodic_cal+0x20e/0x220 [brcmsmac] [<ffffffffa05dce8d>] ? wlc_lcnphy_set_tx_pwr_ctrl+0x21d/0x3c0 [brcmsmac] [<ffffffffa05e0cfc>] wlc_phy_init_lcnphy+0xacc/0x1100 [brcmsmac] [<ffffffffa05e0230>] ? wlc_phy_txpower_recalc_target_lcnphy+0x90/0x90 [brcmsmac] [<ffffffffa05d7c7d>] wlc_phy_init+0xcd/0x170 [brcmsmac] [<ffffffffa05c9dfe>] brcms_b_bsinit.isra.65+0x12e/0x310 [brcmsmac] [<ffffffffa05d061b>] brcms_c_init+0x8fb/0x1170 [brcmsmac] [<ffffffffa05c3a0a>] brcms_init+0x5a/0x70 [brcmsmac] [<ffffffffa05ce76c>] brcms_c_up+0x1ac/0x4a0 [brcmsmac] [<ffffffffa05c3c65>] brcms_up+0x25/0x30 [brcmsmac] [<ffffffffa05c44c0>] brcms_ops_start+0xd0/0x100 [brcmsmac] [...] Signed-off-by: Niels Ole Salscheider <niels_ole@salscheider-online.de> Signed-off-by: John W.
