[PATCH 6.6 047/386] ALSA: mixer_oss: Remove some incorrect kfree_const() usages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 368e4663c557de4a33f321b44e7eeec0a21b2e4e ]

"assigned" and "assigned->name" are allocated in snd_mixer_oss_proc_write()
using kmalloc() and kstrdup(), so there is no point in using kfree_const()
to free these resources.

Switch to the more standard kfree() to free these resources.

This could avoid a memory leak.
