Staging: mt29f_spinand: Replace udelay function with usleep_range
Use 'usleep_range' instead of 'udelay' to elapse time. For spinand_reset, define the upper limit by a factor of 2 to keep the wait short while still allowing a "good enough" range for wakeup. Define the range 250us - 1ms for spinand_cmdfunc to provide enough leeway before issuing spinand_reset. Checkpatch found this issue. CHECK: usleep_range is preferred over udelay; see Documentation/timers/timers-howto.txt Signed-off-by: Eva Rachel Retuya <eraretuya@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
