Hi Krzysztof, Thanks for review. I will fix most of your comment on my next patch. Answering to some of comment/query. On Friday 08 January 2016 07:05 AM, Krzysztof Kozlowski wrote:quoted

Have you run this through checkpatch? And sparse? And coccicheck (that one definitely not because kbuild is complaining)?I ran checkpatch before I sent.
Anyway please be sure that indentation is consistent.

+ chip->rmap[i] = devm_regmap_init_i2c(chip->clients[i], + (const struct regmap_config *)&max77620_regmap_config[i]); Indentation looks weird here (or again this is my email client...). The cast is even weirder?!? Why casting?There is some parameter difference for MAX77620 and MAX20024. I have only one structure for it and changing tun time so I have not define this structure as constant. Now API needs const type structure and hence casting it.
I don't quite get... usually there is no need of casting pointer to a writable memory when function accepts pointer to const.
However, I have define different structure for MAX77620 and MAX20024 which are const type and hence no need to explicitly casting here. This will be in my next patch.
You mean v2? Okay, let's wait for that...
+static inline int max77620_reg_update(struct device *dev, int sid, + unsigned int reg, unsigned int mask, unsigned int val) +{ + struct max77620_chip *chip = dev_get_drvdata(dev); + + return regmap_update_bits(chip->rmap[sid], reg, mask, val); +}quoted
I think all these shouldn't be static inlines in header. Although some of them are one-liners but rest are not. Let the compiler decide what to do with these wrappers.If I dont make inline from header then this will complain as unused static function on related C compilation if it is not used on C. This header included from all sub module driver and they are not using all these APIs. To avoid compilation warning, I need to use inline here.
Because this shouldn't be defined in header at the first place. Instead define it in main MFD driver with EXPORT_SYMBOL() and put in headers just declaration.
