IMHO the best thing you can do is to leave these reads and leave a comment
like "hey, please remove me and test". One day useless reads should be
anyway removed, since ideally rtw_read family must get __must_check
annotation + normal error handling.
No, if these were never getting called in normal operation, there's no
need to add them back.
I guess, I was not clear, sorry. I mean leave reads that were called
during normal operations, but used only for printing debug info. (As
Phillip has already done in v1)
Reads inside R88_DBG() and other debug macros of course should be
removed, but other places seems dangerous without good testing. There is
al least one place with following comment:
/* Although lenc is only used in a debug statement,
* do not remove it as the rtw_read16() call consumes
* 2 bytes from the EEPROM source.
*/
u16 lenc = rtw_read16(adapter, REG_PKTBUF_DBG_DATA_L);
There is a chance that other places have same problem, but don't have a
comment above it. That's why I suggested to leave all these "debug"
reads and leave a comment for further work. It will help to easily spot
them in future and remove or leave them with explanations why.
With regards,
Pavel Skripkin
