-comments:
- - "currently we use a tasklet to detect busy timeouts"
- - "MMC maintainer says this is OKish, but HW timeout would be much better"
- - "this is all for supporting MMC_CAP_ERASE properly"
- - "MMC_CAP_ERASE has been removed meanwhile, and we set max_busy_timeout, too"
- - "we still should care about handling when data timeouts happen"
