ptp_qoriq: don't pass a large struct by value but instead pass it by reference
Passing the struct ptp_clock_info caps by parameter is passing over 130 bytes of data by value on the stack. Optimize this by passing it by reference instead. Also shinks the object code size: Before: text data bss dec hex filename 12596 2160 64 14820 39e4 drivers/ptp/ptp_qoriq.o After: text data bss dec hex filename 12567 2160 64 14791 39c7 drivers/ptp/ptp_qoriq.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: David S.
