Revision bca5c2c550f16d2dc2d21ffb7b4712bd0a7d32a9 authored by Andres Salomon on 12 July 2008, 20:47:54 UTC, committed by Linus Torvalds on 12 July 2008, 21:33:41 UTC
Cortland Setlow pointed out a bug in ov7670.c where the result from ov7670_read() was just being checked for !0, rather than <0. This made me realize that ov7670_read's semantics were rather confusing; it both fills in 'value' with the result, and returns it. This is goes against general kernel convention; so rather than fixing callers, let's fix the function. This makes ov7670_read return <0 in the case of an error, and 0 upon success. Thus, code like: res = ov7670_read(...); if (!res) goto error; ..will work properly.
