Jarod Wilson 559d162e1e [media] hdpvr: reduce latency of i2c read/write w/recycled buffer ... The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <khali@linux-fr.org> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>		2011-01-19 12:52:21 -02:00
