Input: cs40l50-vibra - fix potential NULL dereference in cs40l50_upload_owt()2025-07-04T05:20:46ZYunshui Jiangjiangyunshui@kylinos.cn2025-07-04T04:56:02Zurn:sha1:4cf65845fdd09d711fc7546d60c9abe010956922
The cs40l50_upload_owt() function allocates memory via kmalloc()
without checking for allocation failure, which could lead to a
NULL pointer dereference.
Return -ENOMEM in case allocation fails.

Input: cs40l50 - remove redundant flush_workqueue() calls2025-07-01T18:34:40ZChen Ninichen@iscas.ac.cn2025-07-01T18:33:18Zurn:sha1:6a71a6679fcbe96f894292d6cfc0d58eabf9ac8c
destroy_workqueue() already drains the queue before destroying it, so
there is no need to flush it explicitly.
Remove the redundant 'flush_workqueue()' calls.

Input: cs40l50 - fix wrong usage of INIT_WORK()2024-11-08T05:54:44ZYuan Canyuancan@huawei.com2024-11-08T05:52:23Zurn:sha1:5c822c0ce5cc83ed4cd8394f3dc46dae8d9a681d
In cs40l50_add(), the work_data is a local variable and the work_data.work
should initialize with INIT_WORK_ONSTACK() instead of INIT_WORK().
Small error in cs40l50_erase() also fixed in this commit.

Introduce support for Cirrus Logic Device CS40L50: a
haptic driver with waveform memory, integrated DSP,
and closed-loop algorithms.
The input driver provides the interface for control of
haptic effects through the device.
