2025-02-10tests/qtest: rename qtest_send_prefix and roll-up into qtest_sendAlex Bennée1-1/+0
qtest_send_prefix never actually sent something over the chardev, all it does is print the timestamp to the QTEST_LOG when enabled. So rename the function, make it static, remove the unused CharDev and simplify all the call sites by handling that directly with qtest_send (and qtest_log_send).

2020-07-02riscv_hart: Fix riscv_harts_realize() error API violationsMarkus Armbruster1-9/+5
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. riscv_harts_realize() is wrong that way: it passes @errp to riscv_hart_realize() in a loop. I can't tell offhand whether this can fail. Fix by checking for failure in each iteration.
