Fix alternating tx error / tx buffer not ready bug in QE UEC
The problem is not gcc4 but the code itself. The BD_STATUS() macro can't be used for busy-waiting since it strips the 'volatile' property from the bd variable. gcc3 was working by pure luck.
This is a follow on patch to "Fix the UEC driver bug of QE" (commit daa593ca78c63aadf77aa35c3065d42c535e5ddf). --- drivers/qe/uec.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
