Kelley Nielsen 43fc69b112 staging: ft1000: change values of status return variable in write_dpram32_and_check ... The ft1000 usb driver ignores expected Linux error codes, and uses two values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE 0x1001; and sometimes -1. This patch changes the return value of the function write_dpram_32_and check to 0 or -EREMOTEIO, respectively. The relevant change was made in the helper function check_buffers (which is only called from write_dpram32_and_check); it now returns 0 on success and -EREMOTEIO on failure, and this is allowed to propagate through write_dpram32_and_check. Assignments to the return variable status that are no longer needed were removed as well. In one function up the call chain, dsp_reload in ft1000_hw.c, the status variable was changed from u16 to int to avoid collecting a signed value in an unsigned variable.
