Shouldn't it be avoided?
I'm restoring the OCP_SYSCONFIG register later on, and reusing 'l' here to avoid
confusing expression when moving the sDMA to NoStandby.
I could as well introduce other variable for this...

I could have:
dma_write((sys_fc & (~DMA_SYSCONFIG_MIDLEMODE_MASK)) |
DMA_SYSCONFIG_MIDLEMODE(DMA_IDLEMODE_NO_IDLE),
OCP_SYSCONFIG);
Than I do not need the re-read the CCR, but it looks a bit messy.
I think David is concerned about multiple assigments in one line.
CodingStyle asks to avoid that. So probably:
sys_cf = dma_read(OCP_SYSCONFIG);
l = sys_cf;
would make chekcpatch.pl --strict happy ??
