Subject: spi: tegra114: Use list_is_last() instead of open-coded
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=971e9084beb50c0b244ff95ef2d888f7d158b8a8;p=deliverable%2Flinux.git

spi: tegra114: Use list_is_last() instead of open-coded

For better readability, and then we can remove the comment for last transfer.
