[PATCH -next] spi: Return true/false (not 1/0) from bool function

[PATCH -next] spi: Return true/false (not 1/0) from bool function

[Yang Li]

Return boolean values ("true" or "false") instead of 1 or 0 from bool
function. This fixes the following warnings from coccicheck:

./drivers/spi/spi-s3c64xx.c:385:9-10: WARNING: return of 0/1 in function
's3c64xx_spi_can_dma' with return type bool

It was reported by coccinelle, not robot, wasn't it?

I cannot find this report. This is an open source work and public
collaboration. The "Reported-by" usually means that the issue was
reported. Usually in public. Can we see the report?
Otherwise adding non-public reports is useless and clutters our
report-credit-system.

Yeah, I was similarly confused by the patches on my driver.
Spent some time digging through quarantine systems etc to
try and find the report & couldn't.

I hope I didn't miss something.
