[PATCH 2/4] gpio: zynqmp: Remove unused variable ret

[Ashok Reddy Soma]

From: Algapally Santosh Sagar <santoshsagar.algapally@amd.com>

There is a unused variable ret, due to which we are getting sparse warning
as below.
warning: variable 'ret' set but not used [-Wunused-but-set-variable].

Remove variable ret.

[PATCH 4/4] drivers: mmc: Change datatype to fix a warning

[Ashok Reddy Soma]

From: Algapally Santosh Sagar <santoshsagar.algapally@amd.com>

tuning_loop_counter is of char type. Change to int to fix below warning.
warning: comparison is always false due to limited range of data type.

mmc: zynq_sdhci: Fix wrong tuning_loop_counter datatype

Conceptually description should be done a way that you say I fixed this issue 
because datatype wasn't correct.
And this was reported by spare.

And you are doing it because it is not correct not because there is a warning.
Warning just points to it.

:-) what about return error if get_gpio_modepin fails?
