[PATCH] iio/imu: inv_icm42600: Use max() helper macros

[Bragatheswaran Manickavel]

Use the standard max() helper macros instead of direct
variable comparison using if/else blocks or ternary
operator. Change identified using minmax.cocci
Coccinelle semantic patch.

Re: [PATCH] iio/imu: inv_icm42600: Use max() helper macros

[Jean-Baptiste Maneyrol]

Hello,

thanks for this patch.

The same computation is also done inside inv_icm42600_gyro. Can you do a patch that is updating both files to use max?

Thanks a lot,
JB

Hi Jean,

Same computation can be included in both inv_icm42600_gyro and 
inv_icm42600_buffer.
Will make those changes and send a new patch.

Thanks,
Bragathe
