Subject[PATCH][next] media: cxd2880-spi: fix two memory leaks of dvb_spi
Date
From: Colin Ian King <colin.king@canonical.com>

There are two return paths that do not kfree dvb_spi. Fix the memory
leaks by returning via the exit label fail_adapter that will free
dvi_spi.

Detected by CoverityScan, CID#1475991 ("Resource Leak")

Fixes: cb496cd472af ("media: cxd2880-spi: Add optional vcc regulator")
