I would just suggest to declare these accessors as static and avoid to
export the symbols, especially given their short names. Inlining these
short, frequently-accessed functions is attractive.
+extern u32 dw_readl(struct dw_i2c_dev *dev, int offset);
+extern void dw_writel(struct dw_i2c_dev *dev, u32 b, int offset);
Same here; I don't believe these lines are necessary.
Ack.
Furthermore, I'd like to see this patch at the start at Dirk-san's
patchset. We don't want to make a already proposed patch adapted to
a modified driver.
ack
