Please merge ea8912b788f8 to v5.7 and earlier signal due to scheduling"

Hello,

This commit is in v5.8 but it is affecting users in earlier kernels. I'd like to propose this commit for merging to all earlier stable kernels.

$ git log --oneline -1 ea8912b788f8144e7d32ee61e5ccba45424bef83 ea8912b788f8 media: gpio-ir-tx: improve precision of transmitted signal due to scheduling

Thanks,

Sean
