[PATCH 26/30] ide: Correct LBA setting

Simon Glass sjg at chromium.org
Mon Mar 27 21:07:13 CEST 2023


Fix a longstanding bug where the LBA is calculated as the size of the
media instead of the number of blocks. This was perhaps not noticed
earlier since it prints the correct value first, before setting the wrong
value.

Drop the unnecessary blksz variable while we are here.
