Subject: [PATCH 2/6] ARM: s3c24xx: Improve a size determination in
 s3c2410_iotiming_get()

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
