2021-11-26most: usb: replace snprintf in show functions with sysfs_emitJing Yao1-2/+2
coccicheck complains about the use of snprintf() in sysfs show functions: WARNING use scnprintf or sprintf Use sysfs_emit instead of scnprintf, snprintf or sprintf makes more sense.

2021-10-26most: fix control-message timeoutsJohan Hovold1-2/+3
USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ. Use the common control-message timeout defines for the five-second timeouts.

2021-07-21MOST: cdev: rename 'mod_init' & 'mod_exit' functions to be module-specificRandy Dunlap1-4/+4
Rename module_init & module_exit functions that are named "mod_init" and "mod_exit" so that they are unique in both the System.map file and in initcall_debug output instead of showing up as almost anonymous "mod_init". This is helpful for debugging and in determining how long certain module_init calls take to execute.

2021-04-26Merge tag 'staging-5.13-rc1' of ↵Linus Torvalds3-0/+756
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging/IIO driver updates from Greg KH: "Here is the big set of staging and IIO driver updates for 5.13-rc1. Lots of little churn in here, and some larger churn as well. Major things are: - removal of wimax drivers, no one has this hardware anymore for this failed "experiment". - removal of the Google gasket driver, turns out no one wanted to maintain it or cares about it anymore, so they asked for it to be removed. - comedi finally moves out of the staging directory into drivers/comedi This is one of the oldest kernel subsystems around, being created in the 2.0 kernel days, and was one of the first things added to drivers/staging/ when that was created over 15 years ago. It should have been moved out of staging a long time ago, it's well maintained and used by loads of different devices in the real world every day. Nice to see this finally happen. - so many tiny coding style cleanups it's not funny. Perfect storm of at least 2 different intern project application deadlines combined to provide a huge number of new contributions in this area from people learning how to do kernel development. Great job to everyone involved here. There's also the normal updates for IIO drivers with new IIO drivers and updates all over that subsystem. All of these have been in linux-next for a while with no reported issues" * tag 'staging-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (907 commits) staging: octeon: Use 'for_each_child_of_node' Staging: rtl8723bs: rtw_xmit: fixed tabbing issue staging: rtl8188eu: remove unused function parameters staging: rtl8188eu: cmdThread is a task_struct staging: rtl8188eu: remove constant variable and dead code staging: rtl8188eu: change bLeisurePs' type to bool staging: rtl8723bs: remove empty #ifdef block staging: rtl8723bs: remove unused DBG_871X_LEVEL macro declarations staging: rtl8723bs: split too long line staging: rtl8723bs: fix indentation in if block staging: rtl8723bs: fix code indent issue staging: rtl8723bs: replace DBG_871X_LEVEL logs with netdev_*() staging: rtl8192e: indent statement properly staging: rtl8723bs: Remove led_blink_hdl() and everything related staging: comedi: move out of staging directory staging: rtl8723bs: remove sdio_drv_priv structure staging: rtl8723bs: remove unused argument in function staging: rtl8723bs: remove DBG_871X_SEL_NL macro declaration staging: rtl8723bs: replace DBG_871X_SEL_NL with netdev_dbg() staging: rtl8723bs: fix indentation issue introduced by long line split ...

2020-06-25staging: most: avoid null pointer dereference when iface is nullColin Ian King1-3/+1
In the case where the pointer iface is null then the reporting of this error will dereference iface when printing an error message causing which is not ideal. Since the majority of callers to most_register_interface report an error when -EINVAL is returned a simple fix is to just remove the error message, I doubt it will be missed.

2020-04-28most: core: use function subsys_initcall()Christian Gromm1-1/+1
This patch replaces function module_init() with subsys_initcall(). It is needed to ensure that the core module of the driver is initialized before a component tries to register with the core. This leads to a NULL pointer dereference if the driver is configured as in-tree.
