[PATCH v5 0/3] media: rc: ir-spi: allocate buffer dynamically

[Cosmin Tanislav]

Replace the static transmit buffer with a dynamically allocated one,
removing the limit imposed on the number of pulses to transmit.

Add a check to constrain the carrier frequency inside
ir_spi_set_tx_carrier().

Switch to u64 arithmetic to ir_spi_tx() when calculating the number
of pulses to transmit.

V5:
 * add separate patch to solve overflow issues in ir_spi_tx()
 * avoid overflow in carrier frequency constraint

V4:
 * add separate patch to constrain the carrier frequency

V3:
 * move the allocation to be done per-TX operation

V2:
 * use devm_krealloc_array
