Apply PTR_ERR to the value that was recently assigned.

The semantic match that finds this problem is as follows:

The discussion was about introducing a temporary variable to simplify the
code.  But that makes a lot of changes, so I think it would be better to
just apply the original bug fixing patch as is, and then the cleanup could
be applied on top of that.  I will submit the original patch again.

Yes, that was intentional as the presense of the OSR clock in the DT
node is optional.

"error [gs]etting" could be re-phrased to "could not [gs]et".  The term
"error" was not meant to indicate the log level, but evidently, can
cause some confusion for someone reading the logs.

Where do you suggest to put this?

Maybe it would be reasonable to declare a variable struct clk *clk; at the 
top of the function, and then use that as a temporary variable for all 
three calls.

However, now I see that the first call, unlike the other two doesn't cause 
a return from the function.

if (IS_ERR(drvdata->mi2s_osr_clk[dai_id])) {
dev_warn(>dev,
"%s() error getting mi2s-osr-clk: %ld\n",
__func__,
PTR_ERR(drvdata->mi2s_osr_clk[dai_id]));
}

Is that intentional?

julia

just a note:
using a shorter name instead of drvdata->mi2s_bit_clk[dai_id] whould help to 
make the code
more readable (yes, the other code is alike). something like:

struct clk *tmp =  devm_clk_get(>dev,clk_name);

if (IS_ERR(tmp)) {
dev_err(>dev,"%s() error getting mi2s-bit-clk: %ld\n",__func__, 
PTR_ERR(tmp));
return PTR_ERR(tmp);
}
drvdata->mi2s_bit_clk[dai_id]=tmp;


just one minor:
the dev_warn() just before says: " error getting mi2s-osr-clk" may be it should 
be "warnig ..."
That will make it more easy to rep for real error in a log.

[PATCH 1/2] ASoC: qcom: change PTR_ERR argument

Apply PTR_ERR to the value that was recently assigned.

The semantic match that finds this problem is as follows:

Where do you suggest to put this?

Maybe it would be reasonable to declare a variable struct clk *clk; at the 
top of the function, and then use that as a temporary variable for all 
three calls.

However, now I see that the first call, unlike the other two doesn't cause 
a return from the function.

if (IS_ERR(drvdata-mi2s_osr_clk[dai_id])) {
dev_warn(pdev-dev,
%s() error getting mi2s-osr-clk: %ld\n,
__func__,
PTR_ERR(drvdata-mi2s_osr_clk[dai_id]));
}

Is that intentional?

thanks,
julia

   dev_err(pdev-dev,%s() error getting mi2s-bit-clk: %ld\n,__func__,
