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

[Sean Young <sean@xxxxxxxx>]

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
