ATA8-ACS3, 7.9 DATA SET MANAGEMENT - 06h, DMA
7.9.5 Error Outputs
If the Trim bit is set to one and:
a) the device detects an invalid LBA Range Entry; or
b) count is greater than IDENTIFY DEVICE data word 105
(see 7.16.7.55),
then the device shall return command aborted.
A device may trim one or more LBA Range Entries before it returns
command aborted. See table 209.
This check is not in the common ide_dma_cb() as the range for TRIM
is harder to reach: it is not in LBA/count registers and the buffer has
to be parsed first.
