ARM: omap2: gpmc: Fix gpmc_cs_reserved() return value
Currently gpmc_cs_reserved() return value is somewhat inconsistent, returning a negative value on an error condition, a positive value if the chip select is reserved and zero if it's available. Fix this by returning a boolean value as the function name suggests: * true if the chip select is reserved, * false if it's available Suggested-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Reviewed-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Jon Hunter <jon-hunter@ti.com>
