Subject: [PATCH] SPI: Fix apparently reversed args to time_before().
Signed-off-by: Robert P. J. Day <rpjday@...shcourse.ca>
---
given that the macro this is contained in reads:
#define busy_wait(cond) \
({ \
unsigned long end_jiffies = jiffies + STMP_SPI_TIMEOUT; \
bool succeeded = false; \
do { \
if (cond) { \
succeeded = true; \
break; \
} \
cpu_relax(); \
} while (time_before(jiffies, end_jiffies)); \
succeeded; \
})
it seems obvious that those args are in the wrong order.
