Subject: [PATCH] spi: dln2: Fix reference leak to master
Git-commit: 9b844b087124c1538d05f40fda8a4fec75af55be
Patch-mainline: v5.13-rc1
References: git-fixes

Call spi_master_get() holds the reference count to master device, thus
we need an additional spi_master_put() call to reduce the reference
count, otherwise we will leak a reference to master.

This commit fix it by removing the unnecessary spi_master_get().
