Commit Message

Jinjie Ruan Sept. 4, 2023, 2:14 a.m. UTC
The timeout arg of usb_bulk_msg() is ms already, which has been converted
to jiffies by msecs_to_jiffies() in usb_start_wait_urb(). So fix the usage
by removing the redundant msecs_to_jiffies() in the macros.

And as Hans suggested, also remove msecs_to_jiffies() for the IDLE_TIMEOUT
macro to make it consistent here and so change IDLE_TIMEOUT to
msecs_to_jiffies(IDLE_TIMEOUT) where it is used.

Fixes: e4f86e437164 ("drm: Add Grain Media GM12U320 driver v2")

v2:
- Remove the msecs_to_jiffies() also for IDLE_TIMEOUT.
- Update the fix tag.
- Update the commit message.

Thanks, patch looks good to me:

Reviewed-by: Hans de Goede <hdegoede@redhat.com>

Note I don't gave time to merge this myself atm.

If one of the drm-misc maintainers can pick this up that would
be great.

Regards,

Hans
