Subject: [PATCH] spi: atmel: Let spi core handle validating transfer length
Date: Tue, 25 Feb 2014 19:57:19 +0800	[thread overview]
Message-ID: <1393329439.6723.6.camel@phoenix> (raw)

spi core will handle validating transfer length since commit 4d94bd21b333
"spi: core: Validate length of the transfers in message".
So remove the same checking in this driver.
