patches: add c3 (remove userspace /dev/bes2600 cdev interface)
Fourth stacked patch in the BESser staging-prep series.
remove-chardev-user-interface/
0001-bes2600-remove-userspace-dev-bes2600-character-devic.patch
519-line deletion of the /dev/bes2600 char-device surface:
- open/read/write/release fops and the bes2600_chardev_fops instance
- bes2600_op_* command handlers + bes2600_op_map_tab dispatcher
- bes2600_get_cmd_and_ifname / bes2600_recyle_cmd_and_ifname_mem
string helpers
- bes2600_load_uevent + its call site in
bes2600_chrdev_wifi_force_close_work
- cdev_add / device_create / class_create in bes2600_chrdev_init +
fail label unwind
- cdev_del / device_destroy / class_destroy in bes2600_chrdev_free
- cdev/dev_id/major/minor/class/device fields in struct bes_cdev
Keeps: all in-kernel accessor functions (bes2600_chrdev_is_signal_mode
and friends), the fw_type module parameter, DPD management,
wifi_force_close kernel path (minus the userspace uevent), bus-probe
state machine.
Branch: bes2600/remove-chardev-user-interface (standalone off mobian).
Verified on PineTab2 running linux-pinetab2 6.19.10-danctnix1-1:
loaded bes2600 module is c3's (srcversion 162611C4...),
/dev/bes2600 is absent, WiFi continues to associate, bug #2 (PM
timeout) and bug #3 (SDIO TX splat) remain silenced post-reboot.
