From: Martin Hundebøll <martin@xxxxxxxxxx>
commit bc7f2cd7559c5595dc38b909ae9a8d43e0215994 upstream.
Removing the duplicate gpio chip select level handling in
bcm2835_spi_setup() left the lflags variable uninitialized. Avoid trhe
use of such variable by passing default flags to
gpiochip_request_own_desc().
Fixes: 5e31ba0c0543 ("spi: bcm2835: fix gpio cs level inversion")
