Revision 68ce6688a5baefde30914fc07fc27292dbbe8320 authored by Vladimir Oltean on 28 September 2019, 23:01:39 UTC, committed by David S. Miller on 01 October 2019, 01:32:20 UTC
The speed divisor is used in a context expecting an s64, but it is evaluated using 32-bit arithmetic. To avoid that happening, instead of multiplying by 1,000,000 in the first place, simplify the fraction and do a standard 32 bit division instead. Fixes: f04b514c0ce2 ("taprio: Set default link speed to 10 Mbps in taprio_set_picos_per_byte") Reported-by: Gustavo A. R.
