most: core: Drop device reference after usage in get_channel()

2025-08-28T14:28:45+00:00

commit b47b493d6387ae437098112936f32be27f73516c upstream. In get_channel(), the reference obtained by bus_find_device_by_name() was dropped via put_device() before accessing the device's driver data Move put_device() after usage to avoid potential issues.

most: core: Constify static attribute_group structs

2021-01-26T18:24:51+00:00

The only usage of these is to put their addresses in arrays of pointers to const attribute_groups. Make them const to allow the compiler to put them in read-only memory.

staging: most: avoid null pointer dereference when iface is null

2020-06-25T13:41:17+00:00

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.

most: core: use function subsys_initcall()

2020-04-28T13:04:09+00:00

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.

staging: most: move core files out of the staging area

2020-03-24T12:42:44+00:00

This patch moves the core module to the /drivers/most directory and makes all necessary changes in order to not break the build. Signed-off-by: Christian Gromm Link: https://lore.kernel.org/r/1583845362-26707-2-git-send-email-christian.gromm@microchip.com Signed-off-by: Greg Kroah-Hartman
