Subject: spi: clps711x: Don't call kfree() after spi_master_put/spi_unregister_master
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b4003a687abcf2fe25ba9073dd07345e4529183;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

spi: clps711x: Don't call kfree() after spi_master_put/spi_unregister_master

Calling kfree() to clean up the memory obtained from spi_alloc_master() is
wrong as this is done in spi_master_release() when spi_master->dev's refcount
reaches zero.
