sfc: Clean up waits for flash/EEPROM operations
Make falcon_spi_wait() ignore the write timer - it is only relevant to write commands, it only works for the device that contains VPD, and it might not be initialised properly at all. Rename falcon_spi_fast_wait() to falcon_spi_wait_write(), reflecting its use, and make it wait up to 10 ms (not 1 ms) since buffered writes to EEPROM may take this long to complete. Make both wait functions sleep instead of busy-waiting. Replace wait for command completion at top of falcon_spi_cmd() with a single poll; no command should be running when the function starts. Correct some comments. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
