[PATCH 5.4 084/151] spi: bcm2835: remove use of uninitialized gpio flags variable

[Greg Kroah-Hartman]

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().
