Larry Finger de26859dcf rtlwifi: Fix scheduling while atomic error from commit 49f86ec21c ... Commit 49f86ec21c ("rtlwifi: Change long delays to sleeps") was correct for most cases; however, driver rtl8192ce calls the affected routines while in atomic context. The kernel bug output is as follows: BUG: scheduling while atomic: wpa_supplicant/627/0x00000002 [...] [<ffffffff815c2b39>] __schedule+0x899/0xad0 [<ffffffff815c2dac>] schedule+0x3c/0x90 [<ffffffff815c5bb2>] schedule_hrtimeout_range_clock+0xa2/0x120 [<ffffffff810e8b80>] ? hrtimer_init+0x120/0x120 [<ffffffff815c5ba6>] ? schedule_hrtimeout_range_clock+0x96/0x120 [<ffffffff815c5c43>] schedule_hrtimeout_range+0x13/0x20 [<ffffffff815c568f>] usleep_range+0x4f/0x70 [<ffffffffa0667218>] rtl_rfreg_delay+0x38/0x50 [rtlwifi] [<ffffffffa06dd0e7>] rtl92c_phy_config_rf_with_headerfile+0xc7/0xe0 [rtl8192ce] To fix this bug, three of the changes from delay to sleep are reverted. Unfortunately, one of the changes involves a delay of 50 msec. The calling code will be modified so that this long delay can be avoided; however, this change is being pushed now to fix the problem in kernel 4.6.0.
