/*
 * Check if a device has a specific IP version as well as a stepping within the
 * specified range [from, until).  The lower bound is inclusive, the upper
 * bound is exclusive.  The most common use-case of this macro is for checking
 * bounds for workarounds, which usually have a stepping ("from") at which the
 * hardware issue is first present and another stepping ("until") at which a
 * hardware fix is present and the software workaround is no longer necessary.
 * E.g.,
 *
 *    IS_DISPLAY_VER_STEP(i915, IP_VER(14, 0), STEP_A0, STEP_B2)
 *    IS_DISPLAY_VER_STEP(i915, IP_VER(14, 0), STEP_C0, STEP_FOREVER)
 *
 * "STEP_FOREVER" can be passed as "until" for workarounds that have no upper
 * stepping bound for the specified IP version.
