b43_radio_2057_init_post is not called in an interrupt handler

The function mdelay in it can be replaced with msleep, to reduce busy wait.

You submitted an identical patch a week earlier:

https://patchwork.kernel.org/patch/10137671/

How is this different? Also always add version number to the patch so that the
maintainers can follow the changes easily:

I had negative comments on one of those due to the possibility of msleep(2) 
extending as long as 20 msec. Until the author, or someone else, can test that 
this is OK, then the mdelay(2) can only be replaced with usleep_range(2000, 3000).

NACK for both.

Sorry for my mistake.
I have sent a patch v2 using usleep_range(2000, 3000), and you can have 
a look :)


Thanks,
