--------------------------------

[ Upstream commit 75db7907 ]

The mx25_tsadc_remove() function assumes all non-zero returns are success
but the platform_get_irq() function returns negative on error and
positive non-zero values on success.  It never returns zero, but if it
did then treat that as a success.
