This contains the new module's entry point.
Signed-off-by: Bitterblue Smith <rtl8821cerfe2@xxxxxxxxx>
---
v6:
- Update copyright year.
- Remove some unused includes.
- Make all functions use the prefix "rtl92du".
- Return standard error numbers instead of 1.
- Don't warn about the ips parameter being 0. It is 0 by default.
- Update the commit message to reflect the absence of sw.h, removed in
v4.
v5:
- Call it 802.11n instead of 802.11an in the module description.
v4:
- Delete unnecessary out of memory message.
- Constify rtl8192du_hal_ops, rtl92du_interface_cfg, rtl92du_hal_cfg.
(rtl92du_mod_params can't be const because module_param_named()
doesn't accept it.)
- Move MODULE_* to the bottom of sw.c.
- Delete sw.h and the global mutexes. The mutexes were moved to
struct rtl_priv. sw.h is unnecessary now.
- Add functions to initialise and free the formerly global variables:
curveindex_2g
curveindex_5g
mutex_for_hw_init
mutex_for_power_on_off
v3:
- Add USB ID 2001:330c found by Zenm Chen.
v2:
- Patch is new in v2, split from patch 3/3 in v1.
