staging: most: dim2: do not double-register the same device

2021-11-18T18:16:52+00:00

[ Upstream commit 2ab189164056b05474275bb40caa038a37713061 ] Commit 723de0f9171e ("staging: most: remove device from interface structure") moved registration of driver-provided struct device to the most subsystem. Dim2 used to register the same struct device to provide a custom device attribute. This causes double-registration of the same struct device. Fix that by moving the custom attribute to driver's dev_groups. This moves attribute to the platform_device object, which is a better location for platform-specific attributes anyway.

staging/most: Remove all strcpy() uses in favor of strscpy()

2021-07-27T13:10:41+00:00

strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy(). Signed-off-by: Len Baker Link: https://lore.kernel.org/r/20210717160512.16176-1-len.baker@gmx.com Signed-off-by: Greg Kroah-Hartman

drivers: most: add ALSA sound driver

staging: most: Switch from strlcpy to strscpy

2021-02-04T16:16:06+00:00

strlcpy is marked as deprecated in Documentation/process/deprecated.rst, and there is no functional difference when the caller expects truncation (when not checking the return value). strscpy is relatively better as it also avoids scanning the whole source string.
