Subject: USB: usbtest - add alignment tests to test script
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bc0f23dccad16c7834cb09d943981475be81ddb1;p=linux-beck.git

USB: usbtest - add alignment tests to test script

Enhance the test script to call the new tests added to usbtest
in order to detect host controllers that don't accept byte
aligned DMA.

The unaligned tests are called after their aligned
equivalents but for fewer iterations (since alignment
failure is generally immediate).
