wait_for_completion_timeout returns an unsigned long not int. declare a suitably type timeout and fix up assignment and check.
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Reported-by: Vignesh R <vigneshr@ti.com> Fixes: 140623410536 ("mtd: spi-nor: Add driver for Cadence Quad SPI Flash Controller") ---
Given that CQSPI_TIMEOUT_MS is < INT_MAX the type conversion is actually safe here but it is cleaner to use proper types.
Patch was compile tested with: socfpga_defconfig (implies CONFIG_SPI_CADENCE_QUADSPI=y)
Patch is against 4.18-rc5 (localversion-next is next-20180720)
