Subject: media: mtk-jpeg: Fixes jpeg enc&dec worker sw flow
X-Git-Tag: v6.4-rc1~161^2~336
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=86379bd9d399e2c5fd638a869af223d4910725c3;p=thirdparty%2Fkernel%2Flinux.git

media: mtk-jpeg: Fixes jpeg enc&dec worker sw flow

1. Move removing buffer after sw setting and before hw setting
in enc&dec worker to prevents the operation of removing
the buffer twice if the sw setting fails.
2. Remove the redundant operation of queue work in the
jpegenc irq handler because the jpegenc worker has called
v4l2_m2m_job_finish to do it.

Fixes: 5fb1c2361e56 ("mtk-jpegenc: add jpeg encode worker interface")
Fixes: dedc21500334 ("media: mtk-jpegdec: add jpeg decode worker interface")
