Bluetooth: Remove kernel-doc style comment block

2022-01-21T20:41:51+00:00

This patch changes the kernel-doc style comment block to common comment block. These files don't support kernel-doc style so no need to use the kernel-doc style. Also, they cause the warning when W=1 option is used as below. drivers/bluetooth/hci_ll.c:518: warning: Function parameter or member 'lldev' not described in 'download_firmware' drivers/bluetooth/btmrvl_debugfs.c:29: warning: cannot understand function prototype: 'struct btmrvl_debugfs_data ' drivers/bluetooth/btmrvl_sdio.c:36: warning: expecting prototype for Marvell BT-over-SDIO driver().

Bluetooth: btmrvl: support sysfs initiated firmware coredump

2018-05-29T13:59:50+00:00

Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops") it is possible to initiate a device coredump from user-space. This patch adds support for it in btmrvl_sdio adding the .coredump() driver callback. This makes dump through debugfs obsolete so removing it.

Bluetooth: btmrvl add firmware dump support

2014-12-03T16:35:51+00:00

This patch adds firmware dump support for marvell bluetooth chipset. Currently only SD8897 is supported. This is implemented based on dev_coredump, a new mechnism introduced in kernel 3.18rc3 Firmware dump can be trigger by echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump and when the dump operation is completed, data can be read by cat /sys/class/devcoredump/devcd*/data We have prepared following script to divide fw memory dump data into multiple files based on memory type. [root]# cat btmrvl_split_dump_data.sh #!/bin/bash # usage: ./btmrvl_split_dump_data.sh dump_data fw_dump_data=$1 mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST" for name in ${mem_type[@]} do sed -n "/Start dump $name/,/End dump/p" $fw_dump_data > tmp.$name.log if [ ! -s tmp.$name.log ] then rm -rf tmp.$name.log else # Remove the describle info "Start dump" and "End dump" sed '1d' tmp.$name.log | sed '$d' > /data/$name.log if [ -s /data/$name.log ] then echo "generate /data/$name.log" else sed '1d' tmp.$name.log | sed '$d' > /var/$name.log echo "generate /var/$name.log" fi rm -rf tmp.$name.log fi done Signed-off-by: Xinming Hu Signed-off-by: Cathy Luo Signed-off-by: Avinash Patil Reviewed-by: Johannes Berg Reviewed-by: Marcel Holtmann Signed-off-by: Amitkumar Karwar Signed-off-by: Marcel Holtmann

Bluetooth: replace strict_strtol() with kstrtol()

The usage of strict_strtol() is not preferred, because strict_strtol() is obsolete. Thus, kstrtol() should be used. Signed-off-by: Jingoo Han Acked-by: Marcel Holtmann Signed-off-by: Gustavo Padovan

Bluetooth: btmrvl: use native helpers for debugfs

simple_open: automatically convert to simple_open()

2012-04-05T22:25:50+00:00

Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd Cc: Greg Kroah-Hartman Cc: Al Viro Cc: Julia Lawall Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
