Adding the check for if (sd_check_err_code(chip, SD_NO_CARD)) is good, but introducing the new "reset_pass" variable is wrong. I don't think you are updating the new variable consistently on all paths. For example, if it's a 0x5209 chip and the code is like this: retval = sd_change_bank_voltage(chip, SD_IO_3V3); if (retval != STATUS_SUCCESS) { TRACE_RET(chip, STATUS_FAIL); } In the old system that was considered a successful reset, but under your new system we don't update "reset_pass" here so we pass this test and then we immediately return STATUS_FAIL because reset_pass isn't set. If that's what you intended then just write it like that. retval = sd_change_bank_voltage(chip, SD_IO_3V3); TRACE_RET(chip, STATUS_FAIL); So could you write it again but just set retval = STATUS_FAIL; for the new failure pathes. Or better yet, just return STATUS_FAIL directly. So this code would be: > + if (retval == STATUS_SUCCESS) > + reset_pass = 1; if (retval != STATUS_SUCCESS) TRACE_RET(chip, retval); regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
