• File ccid_common/iso7816_fsm.c:

  • Patch Set #4, Line 271: ip->uart->wtime_deadline = timeout_ms ? (jiffies + timeout_ms) + 1 : 0;

    You are reading 'jiffies', which is incremented by interrupt. I think that this 64 bit read is not atomic, so it may glitch, if an SysTick interrupt fires between reading lower and upper part of that jiffies value. But this is quite unlikely.
