6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
[ Upstream commit 6c6871cdaef96361f6b79a3e45d451a6475df4d6 ]
Mixing SPI slave/target handlers and SPI slave/target controllers using
legacy and modern naming does not work well: there are now two different
callbacks for aborting a slave/target operation, of which only one is
populated, while spi_{slave,target}_abort() check and use only one,
which may be the unpopulated one.
Fix this by merging the slave/target abort callbacks into a single
callback using a union, like is already done for the slave/target flags.
Fixes: b8d3b056a78dcc94 ("spi: introduce new helpers with using modern naming")
