[PATCH 6.1 495/885] media: ti: cal: fix possible memory leak in cal_ctx_create()

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

 



From: Gaosheng Cui <cuigaosheng1@xxxxxxxxxx>

[ Upstream commit 7acd650a0484d92985a0d6d867d980c6dd019885 ]

The memory of ctx is allocated in cal_ctx_create(), but it will
not be freed when cal_ctx_v4l2_init() fails, so add kfree() when
cal_ctx_v4l2_init() fails to fix it.

Fixes: d68a94e98a89 ("media: ti-vpe: cal: Split video device initialization and registration")
