Subject: msm: mdss: Correct the format specifiers in sscanf function
|
|
|
|
In many parts of the code the sscanf function was getting
|
|
an unsigned integer with a wrong format specifier. Changed
|
|
the format specifiers appropriately. Single variable sscanf
|
|
were replaced by kstrtouint at reported places.
|
|
