USB_DT_USB_SSP_CAP_SIZE(ssac) gives the size of the SSP capability descriptor. The descriptor consists of 12 bytes plus a array of SSA entries. The number of SSA entries is stored in a SSAC value in the first 12 bytes, The USB3.1 specification 9.6.2.5 defines SSAC as zero based: "The number of Sublink Speed Attributes = SSAC + 1." This is not intuitive and has already caused some confusion. Make a small modifiaction to the USB_DT_USB_SSP_CAP_SIZE(ssac) definition to make it a bit clearer Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
