Hi,
I'm facing a deadlock regarding a timer callback which is only calling
i2c_transfer(), and I wonder if this comes from that call: I first
googled and found that i2c_transfer() may sleep (which is forbidden in
my timer callback) but when I have a look the beginning of the function,
it starts to check if it is in any atomic context, before trying to
acquire a lock...
So I'm afraid I'm lost and I hope someone will be able to understand to
that question: might i2c_transfer() be used in a timer callback or
should I handle my periodic call to i2c_tranfer() by means of a delayed
work?
Thanks for your reply,
Regards,
Stéphane
