Subject: [PATCH] media: ti: cal: fix possible memory leak in cal_ctx_create()
Git-commit: 7acd650a0484d92985a0d6d867d980c6dd019885
References: git-fixes
Patch-mainline: v6.3-rc1

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.
